Very cleaver game! I really loved the simplistic art style. The game was fun as a puzzle and a platformer. The one sound effect you did have was fitting .The game would be better with some background music. I really did not like how the game did not tell me I could hit W to jump. I spent a long time trying to solve level three because no where in the tutorial it said I could jump with W . Over all very strong game entry, good job, and keep it up!
EDIT: The game was very bitty.
