I've had this game for a while and only recently picked it back up. It's a pretty cool concept and a nice brain exercise for puzzle lovers (not to mention addictive as hell). One big issue, though, is that transition sequences have blindingly bright, totally unnecessary flashing light animations. I have to play this game with my monitor on the lowest brightness setting--otherwise it gives me a migraine.
This game is sort of interesting, but...If you are a heavy puzzle fan who must play everything, go for it, but, I warn you, you've probably seen this before. If you aren't...find a better version. This is a 3d puzzle in which colored pieces drop onto the field while you spin the field so the pieces land on a group of like colored spheres, which will then explode. Detonate a group surrounding another colored piece, and that piece will explode upward and then drop, burning away like colored spheres, and possibly causing more explosions. Quantz's one unique feature is that your pieces are mostly free moving. Shake the field and the pieces move. Shake hard, and everything goes flying, before resettling into a (hopefully) better position. For a puzzle game, Quantz is pretty easy. The only time I've ever failed a stage was I tried to do something fancy, and ignored my timer.
