Nice job! Loved the art and the music, and the little NPCs were a nice touch. I have to agree with the other comments though that the wall jump feels really rough, the rest of the controls feel pretty polished but the wall jump just ruins it for me, especially when its so necessary for most of the levels. I feel like its just something small you'll need to tweak though, get the wall jump polished and you've got a great little game here!
