Back when I was in Secondary School which I was studied in MRSM BPJ, I've learned the existence of this game is quiet overwhelming. It is the most popular game ever and most student playing it in the library.
The game is just like a simple volleyball game but the extra-special of this game is the Pikachu. It's cute and the way Pikachu talked when it's hit the ball is also cute. Hahaha...
By the way, the game setting can be adjusted and including the speed. It can be single player (player vs computer) or two player (player vs player).
