Nice entry, looking good. Well playable. I do have some comments, that I would like to give you. You would have had a much more interesting look and feel by adding some slight animations and / or particle effects. Also the music could have helped you make it feel more intense as we progress the level, the closer to the end, the more energetic, or a higher pitch, would really benefit the game. Overall small changes, would make this game a lot better than it already is.
