there is a demo

And if you can't be arsed with downloading, the demo's also hosted on Kongregate. Great little game.

One of those indie games that I tried to like but didn't.

Better yet, buy it from the official website so he gets more money that way.

And it came with a Steam key anyway when I bought it.

One of the best ways a person can spend $5 :-)

Huh? I bought it before the Steam version was released and I didn't get a key. :(

Once you learn to swear to the beat of the music the game becomes much more enjoyable.

Hahaha! Too true. I didn't like this game when I played the flash version (I thought it had nothing on Metal Storm). After getting the full version in a Steam bundle though, I realized I was totally wrong. This game is great. I even finished it, which seems to be rare for me and games these days.
