Meh.

Pretty good, but nothing too special or too new.

Decent.

I found it kind of amusing for a couple of minutes, though I think it got kinda boring after a while. But then again, I'm not a huge fan of shooters.

Great!

Good concept, easy controls, smooth gameplay and good graphics. This game is awesome.

What. Just, what.

Alright, first off, this is a midi, which you most likely stole from somewhere else. I'm not entirely sure about this, though, you might be the author of the midi, but the chances of that are very slim.

Also, the second part sounds like you've just played 3 versions of the track (all with different pitches) at the same time.
