Has anyone played this? It's a shmup that based its intensity on the music you're listening to. I found about it by accident while looking for Avantasia videos on YouTube. It looks interesting:
It's on Steam and I believe XBLA. And there's a new version, Beat Hazard Ultra, coming out next year.
This game was on sale with 4 other indie games during the Black Friday sales event. Even at $5 for all of the games together, I still couldn't convince myself to buy it.
