Super Puyo Puyo is a fun puzzle game. Unfortunately the game has been overshadowed by the later games in the series. For one thing, the game uses 5 different active Puyo colors in the game, instead of the 4 of later games, making it difficult to put together combos. It also doesn't give you any counter against garbage sent to your side like the later games do.
Outside of that the game is still very fun. Characters are very expressive and even have their own little quirks during cutscenes and gameplay, such as Harpy's poor singing, or Zoh Daimaoh's puyos shaking the screen when they are dropped. Overall a very fun and cute game.
