This felt really good to play. Only frustrating part was the high jump, where you have to stomp on the ground and spring up. I think it was 1 too many actions. Maybe consider going to a crouch and jumping as one smooth motion, rather than having to start mid-air. I'm trying to think of a game that does this...but I'm drawing a blank :D Banjo-Kazooie maybe?
Otherwise pretty cool so far
