I really liked this and was excited to play it. The music rocks and drives the game. The visuals are pretty sleek, and the mechanics are easy enough. Some things off the bat. I didn't quite catch onto how the 10 second theme fit into the game. Maybe it's the length of time between each wave/attack cycle? There was also no clear indication that I was hitting or dealing damage to any of the targets which made me feel like I wasn't accomplishing anything. That hurt the game a bit which is why I docked a couple of stars which I'd gladly give back once those are fixed :)
There's also a bug: I died on the second boss and on restart it wouldn't shoot at me.
