Cool, but big bug...
It's a good go. The game is really well done, and the background/music choosing possibilty is great. But please fix this bug. If I make a block go down faster, then every other block stays stuck in speed drop. So I lose and start over again, and the blacks still fall extra fast (and no, my finger is not stuck on the down arrow). Other than that, it's a very good version of Tetris, for people like me... nostalgics of both Tetris and Mario.
