The game is fine, its a simple beat rhythm game with popular songs. You have basically a "stamina" system in the form of boxes that are timed to open, once you're full, you have to open a box, annoying yes. A practice mode is one huge thing this is missing, because you try to get to a part to practice it and it takes forever just to get there on its own, and if you screw up, restart it. Just an annoying design that puts me off of playing it.
