The premise is too light for my tastes and would get tiring quickly. It's fine for a jam game, but when considering design and depth of design, you might want to push the envelope more. That's subjective, mind you. Just where I come from.
Couldn't land on a single platform. The countrols with the keyboard are really finicky. It's tough to do platforming controls right. I'm no expert. Art and music are good. I love that you had clear instructions on how to play: really important for a game jam game.
