Really good job! It feels, well, very juicy. The camera and animation together just make the game feel so good :). I was having problems with wall jumping, but thats because I was stupid and couldn't figure it out lol.
Two notes though:
1). Maybe have his movement disabled until he touches the ground on a respawn. It could have been just me, but I did tend to fall off the platform quite often before I touched the ground. No. Just me. Wellllllllll
2). Maybe add some text, or something to indicate there is wall jumps and how to do it for those "intellectuals" like my self xD
All together though, great game! I can't wait to see whats next :D
