You might say that its a game jam game, but this honestly looks to me like a prototype of the next hit platformer (successor for snake pass maybe?) I couldn't get pass the gliding part (no idea where to go), but the base concept is really awesome and can be expanded on in many different ways. I hope you make a full game out of this :)
(P.S. not sure if its a bug, but I discovered that if I stick to a wall, face my character so that its side is to that wall, then click to jump a bit and quickly move my mouse back, I can go higher, making it possible to scale vertical walls on my own without doing the wall jump trick. Even if this is a bug, it was really cool when I found it and I had a tonne of fun using that trick, so as far as I'm concerned its an intended feature :))
