I have more than 400 hours in this game, the soundtrack on loop in my car, and the remixes stuck in my head at work. It's best with the included music, but it's not awful with your own, it's fun, it's not hard to learn, and it keeps you coming back for more. Then there's a hard mode (among other game modes in the expansion).

One day I'm gonna have to try it with a dance pad, but that's basically gonna mean learning it all over again. I look forward to 400 more hours, and I highly highly recommend it for anybody who likes roguelikes or rhythm games or cute graphics or daily challenges.
