This was a fairly interesting game. I think its strongest point was how you had a lot of great color effects being used. It wasn't that well detailed, but it really didn't need to be. It reminded me of the "Stick Avalanche" games, which are in fact better. I'm not demeaning you, this was fairly unique in its own right. I was expecting a space shooting game where you attacked the guys that were coming after you.
The music did get a tad loud at times. It seemed like it wasn't really getting harder, it was getting more complicated. It was interesting to not know what obstacle would come up next. I suggest next time you probalby put in a bit more detail. Maybe if you play the game more, you'll enjoy it more.
