Hey ! I created this guide to help you to do somes tricks. We will use this video:

-At the beginning, you can kill the birds by shooting on the tombstone if your gun is loaded. NEW: [0:12] Slide before the load, slide after the tombstone and return yourself to get touch by the ghost, now you need to jump at the top of the ladder before grabing it. Slide, jump, slide again and pause two times the game while falling (let a bit of time between the two. Now slide. If you did perfectly all of this you will get the early cycle. This is really hard. -[1:06] When you slide below the spikes, tap Enter (menu) 2 times and jump at the left, you will zip a little further. -[1:24] Go on the top of the ladder, climb back down, and die on the hole. You will respawn at the top of the next room. NEW: -[2:38] Ham Skip: Jump and keep pausing until you are on the plateform NEW: -[2:50] Jump and spam enter, this can be quite hard to get but if you are fast enough, you will be able to get an early cicle on the next clouds -[3:01] If you are at the edge of the platform and you jump, you can skip the next platform (Failed on the video) [NEW] After this, position you on the middle on the ladder, jump and don't grab it, you will be able to skip it -[3:11] When the platform moves down, you can jump directly to the other platform, [NEW] if you did the ladder skip+you played well, you will be able to get the first cycle here. -[Final Boss] You can manipulte the boss when you are on the lader: When you are at the top of the ladder, the boss will climb the other ladder, you can shoot him like this.(charged shots for max dmg) When you are at the down or at the middle of the lader, the boss will try to shoot you on the ground. The boss loses his invulnerability when he touches the ground.

-When you need to be hit by a monster, turn back, the knockback will be reversed.
