your game is really fun and hard! I love the art in the game and the little guy.
For the movement on the character, I kept sliding which made staying on the platforms difficult, and in level 2 it feels like I can't jump as high as I did in level 1. Also, on a couple platforms, I don't know why this happened, but I would suddenly just be stopped. And at the top the camera doesn't follow all the way so the little guy's head gets cut off.
