The game's a bit short and a bit unfinished, but I think you have an amazing foundation for a game right here. The game makes great use with the time it has with its creative and fun level ideas. If you were to add some music and audio, improve upon some of the art (the pushable box IS just a white square) and add some more levels, you might have an amazing game on your hands. In short, I think you did a good job on this game. Well done!
