The best falling block concept since Tetris. The ability to attack your opponent with your performance added such a level of chaos to this genre that would be replicated by numerous other games in future years. It forces you to play faster to outdo your opponent and in turn it basically makes the entire concept more challenging because the better your opponent is, the more it forces you to play even faster to outperform them. I like the art style, and the silly voice acting, but I love the gameplay, it's just pure catnip to me.
