After wall jump its not really obvious that you have to fall down in the pit to continue. I wonder what happens if you fall before you get the wall jump, hm...
Anyway, nicely done, I managed to get to the end. Few simple but nicely executed ideas in a level, its not just running and jumping, great. Cool animations and graphics, nice sounds. More! Because now I wish it was a tiny bit longer, and that's the only problem I think;)
