This is great fun to play. The pistol sound effects and feedback are excellent - I'd love to see this kind of shooting in other games. You move at a constant pace through each level (which doesn't trigger my motion sickness. Bad guys appear, and you're meant to shoot them in time to the music. Overall it's really polished and good fun. The soundtrack is ok, although the main problem I have with it is that at it's heart, this is a rhythm game and you get points for shooting enemies in time with the music. In lots of the tracks I can't hear the beat, or it's not strong enough to know when you're meant to shoot people. Badly needs to support modded songs, otherwise it's pretty short.
