Epic Style Glitches and Speed Tech

Left facing spike clip:
By changing your horizontal parity by either empty dashing (dash without giving a directional input) or walking into the right side of a wall, you can walljump off of left facing spikes. This works because your x position is always even and by changing your parity to get an odd x position you can get just barely close enough to left facing spikes to wall jump off of them.
https://imgur.com/H44L24H.gif

Up facing spike clip:
Spikes in Celeste wont kill you if you're moving away from them. So if your vertical velocity is negative* (you're moving away from the spikes) but its not actually high enough for you to move a pixel, you will be able to clip the spike. This is normally done by lining up the apex of your dash with the spikes

*If the negative part sounds weird, trust me there's a logical reason for it
https://imgur.com/W44IvSn.gif

Down facing spike clip:
Nothing much to say here. If you're moving fast enough you can straight up go through the spikes. This allows you to clip the spikes at the top of 2500m and save loads of time
https://imgur.com/dlJNfEP.gif

Right facing spike clip:
Doesn't exist PogChamp

Grace jump/Coyote jump:
Once madeline walks off a platform, she has 6 frames in which she can still jump.
https://imgur.com/KLhBU2Z.gif

Corner jump:
While its named corner jumping and it looks like you're jumping off of the corner of the block, what you're really doing is wall jumping off of the left/right side of the wall but right after passing beneath the corner of the block. See how taseline performs 2 of these at the end of the gif.
https://imgur.com/KLhBU2Z.gif

Gem skip:
By dashing the frame before the chest animation freezes madeline, you can buffer a dash that will happen once the chest animation is over, however you will regain your dash after this buffered dash allowing you to skip the gem. This works because when you hit dash you freeze for 2 frames before dashing.

Double walljump:
In the words of @Juice
"yeah you get height because
the first one is right next to the wall
so you stay close enough in to get back and gain height
but the second one is a bit away from the wall
so you can't gain height indefinitely
only once"

Cloud boosting:
The top of a cloud is a solid platform that you can walk on so if you dash up into a cloud you can regain your dash back and also quickly jump from the cloud allowing for better movement.
https://imgur.com/2aAYE6T.gif

Berry block suction thingy mabob:
In the words of @Meep_Moop
"You have to be touching the block
Then dashing away from the block
while still touching it
And it tries to bounce you in the opposite direction you're traveling in
So it bounces you into the block"

The Gem-Skip any% Tutorial

__Edit 2021-03-10__:
gonengazit has edited this guide to give a more accurate overview of the easiest and best strats, thanks to discoveries from the last 2 years.

# Introduction
   Hey there, welcome to the gem-skip any% tutorial! Before we start I
   just want to give a huge shoutout to everyone who contributed to this
   category: Meep, justinj, and many other people, and also to everyone
   in the Celeste Classic community, you guys are awesome! This category
   is actually pretty hard, but with enough practice you can get a
   pretty good run and maybe even go for WR (which is pretty free right
   now let's be honest). So let's get started.  
   
   First of all, be sure you have enough time to actually do a first run
   of this, it can take about 2/1.5 hours to do it without any practice,
   and only a handful people have even completed a gemskip run deathless.
   
   As I said earlier, you don't really need to go for the fastest strats
   or have a good pre-gem, most levels are hard enough to make you die
   at least a few times. The way I'd recommend starting to run this is
   by starting a run and learning the strats as you play.
   
   I'll only cover the levels that actually change from regular any%, if
   you're running this you probably know how to do everything pre-gem.
   
   If you want, here are links to most of the gifs used in this tutorial: https://imgur.com/a/OLsBjz4 https://imgur.com/a/CKM3Ztn
   
   
   
# 2200m
   There are 2 possible approaches for 2200m- chestful, where you abuse the chest animation to get enough height to exit, or chestskip, where instead you get a boost. Chestful is generally considered easier and more beginner friendly, but chestskip is faster, and can also serve as a backup if you've opened the chest.
   
   There are mainly two differents strats that can be done for chestful,
   this one is the easiest and best strat to start with:
   
   https://i.imgur.com/4nh7bDg.gif
   
   The one below is a faster way to do it (even faster than regular
   any%) and can be pretty consistent.
   
   https://i.imgur.com/NwZ70Sb.gif
   
   On both strats you're basically doing the same thing: dashing at the
   same time you open the chest. You'll know it worked when your hair is
   blue while the chest animation is playing. After that you just want
   to spam jump while the animation is playing and then dash up when you have enough height.
   
   For chestskip there are also 2 approaches:
   
   This one is easier to execute and  also isn't based on your initial position in the level:
   
   https://i.imgur.com/F5KGR9x.gif
   
   You want to stand in the ditch, then jump, and dash here without wallsliding beforehand:
   https://cdn.discordapp.com/attachments/496751398831259669/742664165017124924/unknown.png
   
   Afterwards, you want to wallslide all the way down, and jump here:
   https://cdn.discordapp.com/attachments/496751398831259669/742664334605418526/unknown.png
   
   If you do it all correctly, you should regain your red hair while rising up, and then you can then jump and updash towards the exit.
   
   The second chestskip strat is the fastest known way to complete the level:
   
   https://i.imgur.com/Cn1kvzy.gif
   
   Buffer an upright dash, buffer a jump, and then right dash around when madeline's center is above the edge of the chest. afterwards, buffer a left press, and walljump a frame before landing on the ground. If you do it all correctly, you should boost as before. Note that this strat is very precise, and isn't recommended except at the highest levels of play.
   
# 2300m
   
   Now things start to get a bit more complicated, this level is one of
   the harder ones when you're starting to run this category so don't
   feel bad if you don't get it.
   
   For this strat you can choose to do a double walljump or not. It's usually considered easier to do a single walljump which looks like this:
   
   https://i.imgur.com/J6FwHw8.gif
   
   The double walljump strat looks like this:
   
   
   https://i.imgur.com/wH8P0U2.gif
   
   
   The only thing you have to note when doing double walljump is that
   you can't do the first walljump as soon as possible, you have to grab
   the wall a bit more and then start spamming jump for the next one.
   The double walljump will give you 1 pixel (or so) of extra height so
   you can reach that cornerjump more easily.
   
   The double walljump strat is a bit slower, but unless the run you
   want to beat is deathless and super optimized it doesn't really
   matter, and you should do what's more comfortable for you.

   
   For the first diagonal dash you don't want to be too close to the
   border of the level or the platform you start on, somewhere in the
   middle should be fine.   As you can see in the input display, after
   the up dash you spam jump, hold right and hope you get it. This is
   the same for both strats.
   
# 2400m
   
   You can do this level many different ways, the way I do it is like
   this: 
   
   https://i.imgur.com/P15FkvL.gif
   If you're running this on new Celeste, you can't do the strat like
   this, you have to go to the left until you hit the end of the level,
   go back and then do the rest of the strat normally (you should be
   running this on regular Pico-8 though).
   
   Here are a few different strats for the ending:
   
   https://i.imgur.com/1hyBluH.gif

   https://i.imgur.com/OCIFAEw.gif
   These 2 strats do basically the exact same inputs to start, and you can react to which you get for the exit.
   On the block, quickly turn left then dash, then buffer a jump. If you get blue hair, just spam jump and you can cornerjump out. If not, you can do a late upleft dash, and reach the left wall
   
   https://i.imgur.com/ZNTgh8J.gif
   For this strat, position madeline so that her left foot is 1 pixel away from the ground, then do an empty dash. You should then be able to upleft dash, and cornerjump/walljump out.
   
   The start can be done like this:
   https://i.imgur.com/rmXYxUw.gif
   You can do whatever beginning/ending strat you want, whatever makes
   you more consistent at it works. This level and the next ones aren't
   too bad to do, but get ready for 2700m.
   
# 2500m
   
   This level is pretty easy, there's only one good beginner strat to do, which
   is this:
   
   
   https://i.imgur.com/646Nnep.gif
   Jumping after the first dash makes it easier to do the up dash after
   the first spring.]
   
   There's another strat that I won't go in much detail which involves
   the ceiling spike clip done in any%, it's pretty hard and you
   probably shouldn't do it unless you have a deathless run and are going for some pretty fast times. If you want to, though you can do something like this:
   https://i.imgur.com/uqdcJyq.gif
   
# 2600m
   
   For 2600m the only strat I know of is this:
   https://i.imgur.com/ZT2Td2A.gif
   The beginning is pretty simple, after you do that and get to the
   platform next to the spikes, you want to jump, dash up and try to
   walljump at the right time so you can get the cornerjump, this is the
   same ending used in the faster strat of any%.

# 2700m
   Oh boy.
Now this is the hardest level in the run (and maybe in any category of this game), this is the "safe" strat:
https://i.imgur.com/PPHZRmp.gif

Now let's break this down.
For the beginning done in the gif you want to start the level by holding jump and right, then upright dash when madeline is here:
https://i.imgur.com/hN3JZ9r.jpg

After that, hold left, and updash in the same height as the gif, then hold right. If you timed everything correctly, you should clip the spikes, and be able to reach the other side.

There are a few variations for the beginning and the end of this strat. 
You could start with an empty dash and do a spikejump like so:
https://i.imgur.com/FMNoLs9.gif
you can check out a detailed overview for cues for this strat [here](https://docs.google.com/document/d/1uO1tD9stDKuzuUrl_H61fUNjwERs3XOFpo4aDFwakJQ/edit?usp=sharing)

You can also start with a regular right dash and and just dash up to get the balloon without doing the spike walljump, which would look like this:
https://i.imgur.com/GD9tiLV.gif

With these variations you might have to jump right after you spike clip, or you'll die like I did in the 3rd gif.
After you get past this, you have to start going towards the left wall, walljump at the right time and then up dash. You can't wait too long to do the walljump or you'll be too low on the wall with the balloon and might not be able to reach the exit. After you get the balloon, spam jump and hold left, you want to stay on that wall and try not to lose too much height, you'll want to wait for the balloon to respawn and then when you're coming back from a walljump do an up dash, go left, walljump then another up dash to leave the room. At the wall with the balloon, some people also prefer to do the up dash right after they do the walljump instead of doing it on their way back, do whatever you feel more comfortable with.

So let's say the strat above is *way* too easy for you and you want to take your torture to the next level, well you're in luck.
https://i.imgur.com/fhbe2kG.gif

In theory you could do this with any beginning, but I highly recommend doing the first one if you go for this, becuase it gives you the most consistent subpixels. The main hard part of the strat is the ending. You have to walljump at the perfect height so you can reach that cornerjump without dying to the spikes or simply not making it at all. This is a very hard strat, and I only recommend you do it once you've got a deathless run and are trying to get a very good time.
After you do this, the next levels aren't so bad.

# 2800m
This strat is probably the best one to do on this level:
https://i.imgur.com/lvqJdzx.gif
The only tricky part about this level is getting the double cornerjump at the balloon, for this you need to check the height of the balloon at the start of the level: if it's going down then you'll probably have to wait a bit until you go for the cornerjump, otherwise you can (probably) make it without any problems. 
When you're dashing from the crumble blocks to the balloon you don't want to be too much to the right or you'll not get your dash back. After grabbing the balloon go a bit left and dash up, then go full left until you hit the other crumble, your parity should be right so you can just spike walljump off the wall to the right, then hold left and spam jump to exit.
instead of dashing off, you can try walking off and jumping late. I personally prefer dashing off, but you should mess around and do the one you're more comfortable with.

# 2900m
This strat is almost the same as the one in any%, and goes like this:
https://i.imgur.com/YuAFDDJ.gif
The only thing that changes is the way you exit, you don't have the two dashes so you have to go right to get the balloon, walljump and then dash diagonally to finally exit. I don't really have much to say about this strat, it's the same start as the any% one so you just have to get the timing right.

You can also do it like this:
https://i.imgur.com/tAFAKYF.gif


There's also a harder, but faster strat that you can do:
https://imgur.com/jRQyZDk.gif

the basic idea is: buffer a jump off the spikeclip, then at the correct time walljump and 1 frame later upright dash, and if done correctly, you'll clip the spikes.



# 3000m
You're almost there! This level is not so bad too. There's one main way to do it:
https://i.imgur.com/I6hxdtJ.gif

You want to walk off the crumble block, then upright dash in between the spikes. After the dash you want to release all directional input, and walljump off the block. If you did this correctly, you should clip the spikes, and be able to exit.
Instead of the ending shown in the gif, you can veer left and upright dash, which could be a bit easier:
https://i.imgur.com/9p517ty.gif

If you don't want to do that strat for some reason, there's a different one you can do (though this strat is slower and a bit harder, so not very recommended).
There are two different ways to start it, I'll start with the one I do, which is this:
https://i.imgur.com/YmZlIRU.gif
This start is more rythm based, you want to start holding dash + down + right and you'll line up with the balloon so you can dash up to do the spike clip. I try to do the dash after getting the balloon at the same height as the first spike on the right wall. 
The other strat looks like this:
https://i.imgur.com/CRtnssr.gif
It's basically the same but without the dash at the start, in my opinion it's way harder to line up than the first one, but some people think it's better like this.

So, if you followed the tutorial, you reached the summit with a nice red hair! Congratulations! Be sure to check out our Discord to get that gem-skip role as a reward for all your suffering, and submit your run to the leaderboards. See ya!

Version Differences

First, what are the different versions available? They are as follows:
Webleste (The website variation)
Newleste (The easter egg in the Steam and Epic Games releases of the game)
The Standalone (The downloadable version found under resources)
Pico-8 (The cart that lets you run the game in pico-8)

Now generally speaking all the versions are mostly the same however there are a few key differences.

The first key difference is that players using the webleste version tend to be far more susceptible to missed inputs and input lag than players using any other version of the game however for some players with potato pc's it can be less laggy like it was for me when I first started running

The second and biggest key difference however is that the newleste variation isnt actually a 1:1 copy of the other variations. The reason for this is that the other versions are written in Lua whilst the port on newleste is written in C#. During this conversion process one key piece of tech was removed and that is empty dashing. For those who are unaware empty dashing is dashing without giving a directional input and can be used to change your parity and walljump off of left facing spikes. Due to its removal, 2700m is harder in the gemskip category as you cannot empty dash at the start, and a slightly slower but in my opinion more consistent method of fast-1800 is also impossible. Another quirk of the newleste port is that when executing fast-2500 you actually die for I believe a single frame when clipping the spikes on the ceiling losing you very minimal time.

Anyway thats a quick wrap up of the different version differences.
