In contrast to what some other people said, the controlls feel very tight to me. I can get my character exactly where I want it, which makes for excellent platforming!
The levels are also very thought out, as they work perfectly from different sides without moving the obstacles (like some ot her jam games do)
My only nitpick is that it would be nice to have some pointer as to where the next goal is, but apart from that very well done!
EDIT: also I'd suggest adding a timer, because I see great spedrun potential
