Super clever idea! I wish there was a bit more regularity to shape movements, it was really hard to get try to get things to line up (though it doesn't help that i suck even at normal tetris)
Yea, I also notice if one shape keeps moving to one side, the player is very limited in his options, I planned to reduce the propability to move in one direction, when the shape already moved in that direction, but didn't have the right idea how to implement it at that time.
