escape 0 is possible with the boost that you get from starting to wall run (you need 3 walls to gain the needed height), and sky 2 is possible with the same mechanic + a glitch to get on 2 platforms ()

I have no idea if this has been suggested before, according to TAS (yeah I know how it sounds) the game is fully completable without using jumps. It is hard but DEFINITELY doable. I am typing this between runs of the currently 100% possible levels.
