Not Tetris 3

Something is different about this game, I don't think it's really Tetris. 

Play through this twist on the classic and see what surprises are in store. 

Controls: 
Move the piece left and right with A and D. 
Accelerate the piece downwards and reduce its  sideways and rotational velocity with S. 
Rotate clockwise and counterclockwise with E and Q respectively. 

Please let me know if there is a problem with the Mac OS version!
