I like the music choice for your game and the ability to change skins. Some things I'd suggest...
- Add some sort of scoring system so players can tell if they got far in a playthrough or not. It gives players something to strive for new highscores easy
- Add some variability to the game, for instance the longer you play, maybe the game gradually becomes harder the further you get in a playthrough.
P.S. I think the team members section of this page should say the names of team members instead of a number.
