Very fun game and nice amount of levels :)
Only thing I would say to make this game better, is to add some coyote time, where the player has half a second extra to make the jump after leaving the platform.
I debated the whole jump mechanic issue for a while :). In the end, felt the Shimmying up the wall was a fun addition for a jam game. Though future versions I need to commit one way or another to it.
Coyote jump may well be the best compromise :). Great suggestion, thanks!
Thanks for playing and for the feedback!
