Dang, this game is very creative. First I really like the main menu, definitely way different than all the other ones and just shows that you put in a lot of effort. The rhythm-based shooting is also very creative, and the music and audio is nice. But you can probably juice the game up a bit more, add like blood, screen shake, particles, etc or just make the shooting sound less repetitive. But with only 1 week, I think you managed to get a lot done so great job!
