Wonderful, but it has some problems...
The gameplay is incredibly addcting, especially to people who like Tetris in general, but the loose controls make it a little hard to play. Plus, it has some major glitches like being able to flip out of a tight spot by going through a brick is just about to land. That, the fact that you can flip into a wall and die, and the fact that you can get squashed by blocks that SHOULDN'T crush you definitely takes away some of the charm. It's addicting gameplay still manages to make up for most of that though. All in all, I'd give it 8/10, 4/5
