I'm absolutely terrible at rhythm games, lol. Still, this is probably the rhythm game that I played the longest. Everything is so polished and nice. The movement is responsive and snappy and perspective is spot on. Great looking dungeon textures too. Sometimes I'm rotated twice when turning, but that's no biggie. The map (and how it appears) is real nice and the way you add to it as one progress is cool.
+1 for numpad controls!
Great job :)
