This was nothing special about this game. It was pretty much just these bland shapes shooting over and over. I liked how I was able to richochet some of the ammo. Of course, that only lasted so long. The music is quite nice, though. It's nothing noteworthy.
You should have had better designs. It was just simple shapes over and over. You could have also had health bars on the enemies. It got frustrating like that. I could build some good defense eventually.
