This is a fun game – it feels a bit simple, but it is certainly challenging. I would put this game in Tier One, except for one thing – I’ve played Thumper. I’m not suggesting that these are the same games – but they’re the same type of rhythm avoidance game, and Thumper is the far more enjoyable one. Still, I will likely pick this up after playing out Thumper, and there are far worse things you can spend $3 on. Unless you get motion sick – in which case, this is probably the worst thing to spend money on. See that screenshot? Everything is spinning and you’re the triangle.
