Groove Coaster is a textbook example of how to make an iOS game correctly. Simple one-finger controls and quick play sessions belie a game with a considerable amount of depth and replay value.
The minimalist graphics, like in the game’s predecessor Space Invaders Infinity Gene, manage to be gorgeous, clean, crisp and simple all at once. And the soundtrack -- the key part of any rhythm game -- is diverse enough to feature at least one track to appeal to everyone.
In short, this is a game that you need on your iOS device.
