Pretty cool!! I love when developers turn a single player puzzle game into a multiplayer action versus game! It's even got a story mode where you fight a little tiny living onigiri for some reason! The only issues I have is that there is no garbage margin, or pressure system to keep the game from going on for 40 years. I don't want something as ham-fisted as modern Tetris, where there is UNCLEARABLE garbage stacking up from the bottom, I would want something more like Puyo Puyo, in which the amount of garbage sent slowly, subtly increases with time until both players are sending mountains of nuisance blocks with every move, making mistakes mean more and more bad the longer the game goes on.
