fair enough, this is intended as a straightforward Tetris clone, with focus on adding wall kicks and a quality of life enhancement in the ghost piece. I admit the modifications would have been more obvious with the addition of more modes, especially a 2-player mode, it just wasn't possible to do in the time frame. At least in the existing Amiga versions I tried I could see anything like Super Rotation System, which was a development added in 1991.
