That was strange. It have potential and cool concept, but you wasn't able to accomplish much in time.
Level is also too short, i think it's not really going with theme, but as i see from your comment it's because of time.
I would not repeat what other have sad, but will add one thing - next time enable Restart Button after win. I restarted the game in order to experiment with mechanics, cause restart button didn't work after win.
