Shrine animation skip

If you hold a direction button before speaking to any shrine, you'll skip the acceleration for scrap donation. Can also be buffered with Down+Right/Left. Even though it doesnt save IGT, it does save you some time of donating big amounts of scrap

Save & Quit skips

• If you Save and Quit after pressing one of the switches in Megabeast Core, you'll skip the entire fight sequence.

• You can repeat Megabeast fight after killing it to farm achievements, if you S&Q right after getting each kill achievement window.

• Since runs are timed with IGT, you can do S&Q to skip certain animations, like respawning/saving on a Revenant Station, or going back all the way to the start of any room for farming purposes.

Glitch realm access

There are 4 ways of accessing Glitch Realm:

• Donating 4 of each 4 scraps to a shrine
• Dashing into a non-used Revenant Station (not sure if doing Buzzsaw Shell screw attack into it counts too)
• Talking to Tutorial Smith if he has a glitched animation (only available after accessing Glitch Realm for the first time)
• Going out of bounds (Phase Shell, Arachnomorph damage boost, Dashing into a magic pixel, touching that one item block inside The Factory horizontal room with spikes and moving platforms)

Slideboost

If you do a slide, then press jump + the direction you're going, you'll be boosted in that direction. This scales both with Dash, and with how much Speed you have in the moment, allowing you to traverse wide rooms quick. Note that having Buzzsaw Shell will render this tech undoable.

Forest room skip

A totally not useful way of skipping a room in forest. Somersault into a branch with less than 1 block size, then shoot as soon as you're touching the floor. Somersault has a smaller collision than shooting hitbox, so you'll get pushed below the branch when switching animation.

Stacked hitboxes

Some bosses can be killed quickly if you shoot them with a penetrative shot (Buzzsaw Gun, Penetration Bolt or Electrocharge) while the boss fight is starting (while Get Ready text is on screen). Quick examples are Wall Creep, Flesh Adder and Megabeast

Phase Shot switch skips

• If you have enough Bolt Size (preferably with Electrocharge), you can make the explosion of the bolt go through walls and hit any Phase switch

Surface City tall room skip

There are few specific ways to skip this room without Infinite Jump upgrades. Most of them will require walljumping off the ledges on the top of the room.

• If you have any High Jump pickup (except Hover Boots), you can get damage boosted after doing a big jump, so you can chain the resulting somersault with a wall-jump onto the ledges.

• In the case of Hover Boots, these require a different setup with walljump and hover, to get damage boosted and continue hover upwards. It's way more precise than other HJ pickups

• If you DONT have high jump, but you have 21 or more speed (the more speed, the more consistent it is), you can do a wide walljump onto the ledges to get up there. Doesn't need any damage boost but its a huge speed requirement. The NJ Jump :^) Can be obtained with 18 speed and temporal upgrades (from champions or Wadjet Mikail) or more speed.

• Really precise Damage Boost (which have random direction and intensity) if less than 20 speed, to get the wall jump and same as above.

• There's a last way which requires both a High Jump upgrade + Red Key but that's really situational and just means triple jumping as normal.
