I'm still thinking about it... You said the floating is wrong there - you mean it should fall faster? I agree with that.

In the level where the restart button is introduced you can barely make the jump by using the floating mechanic which is cool. But I didn't find out about the floating in that level or the one before (you don't have to, to solve the level) . I thought I got up (after many tries) because I pushed the jump button harder. At that time I didn't know about the floating and because the wall isn't flat the floating would make you "wall-jump" sometimes.
TL;DR Jumping while floating against a wall was what felt a little weird I guess.
