Just bought it, well done! The only option I would love to see is being able to select only one "Next" piece to show (coming from Tetris DX, I often get mixed up with all the "next" pieces in the corner of my eye). Also, I think I got a bug when after finishing all lines in Marathon mode after the completed screen the game hung on the title screen with strange sounds playing: video
I'm playing on an EZFlash Omega DE, btw.
