The animation doesn't really feel fluid , seems like the character is jumping from 1 frame to another : The punch animation ends , jumps to idle ; when up is pressed , left pressed , jumps to running animation (Maybe it's me , I can't really compare it to limbo :) ) the wall jump is a bit hard to achieve , the difficulty curve is too harsh , died on the second bunny , the punch doesn't feel smooth ( when you punch repeatedly , you can see a delay between each punch , I guess it's the animation ) and more acceleration (inertia) wouldn't hurt , I guess all of this would change in the full game ...
