frustratingly both really fun and too difficult and luck dependent for me to really get into. the game does a REALLY good job at making you want to beat it, though, by making the enemy robots look like the stupidest fucking assholes. make no mistake: they fucked your girlfriend AND your mother and have FULL intentions of continuing to do so. you just NEED to destroy them so bad and every time you lose they snicker right at your face and would probably start teabagging you if this was a different kind of game.

Made entirely obsolete by basically any subsequent Puyo Puyo game. Without offset or other key mechanics that came to the series later (such as double tapping rotate to flip your puyos even if they don't have room to rotate), victory in the arcade mode becomes very dependent on luck.
I have too strong feelings about American Sega's apparent need during the 90s to project their own (entirely ill-defined) fan-fictionesque personality, worldbuilding, and character designs onto Sonic, and while this game serves as a key example of that, that feels like a rant ill-suited for a review of the game itself.
