Known Glitches and Skips

V1.1

Air Walking - In this game it appears you can continually jump slightly before you hit the ground. This apparently also works on the killbox. So you can walk off a ledge and by mashing the jump button / key you can continue to jump on thin air and go all the way to the end of level 1 and level 4 on patch 1.1

Slide Jumps - By using a ragdoll animation like 'relax' and pressing the slide key while in the ragdoll state you will queue the slide animation, but not slide. During this animation you can mash jump to jump very high and even retain control of the direction your character moves. This can help you reach the end of level 2 immediately and skip large sections of level 5.

Long Jumps - By jumping almost immediately after sliding you can do a very long jump. This isn't currently used in any of the runs.

V1.2 

Air Walking - Still works but the devs moved the killbox far lower in Level 4, making walking to the end of that level using Air Walking apparently impossible. It still works on Level 1.
