on level 64 it is possible to one cycle the level. altho it took me over an hour and a half to get it once. don't think it will be helpful in runs but just wanted to get it out there.

The way that ended up working for me the best is to just almost one frame after the level loads in I do a full jump and then when I touch the platform I try and do the smallest jump that I can and then you have to do a full jump after that then after that you just have to try and hit the ice blocks above you as fast as you can and then hope that you time the last jump just right to make it on the elevator up.

on level 80 you can fall down on the left side to go faster
