It's awesome. Could definetly be the next crossy roads.
Maybe try lower the hit box for the tree when the player is more close on the side of the tree. when hitting it more head on it feels pretty fair though. But a couple of times I felt like i was past the tree but the hit box didn't have leanancy depending on far past the tree I had traveled. Sorry i'm super tired so sorry if that was expressed terribly.
Also sometimes the cliff face graphics especially the more elevated bits can be a bit confusing in a detracting way. Hard to tell top of cliff from slope at least for me.
Also I would probably start it slightly slower. But that might just be because im tired atm haha.
