I recently bought this game, and I haven't put it down since! The game is controlled with 4 buttons, which you beat in different rhythms to control your army of pons. There's lots of fun to be had playing all the little side games, and the cute graphics add to the game's fun. The music is completely random and you just get lost in the beat!!! (Look out for the dancing tree ,UBO BON...) I've been playing this game for nearly 8 hours, and I'm nowhere near finishing, so this game offers plenty of playing time. At times, this game is quite challenging, and it takes a certain amount of skill to navigate some battles! However, this offers fun for all, and I would seriously recommend this game to anyone! Worth the money in my opinion, and one of the most enjoyable titles on the PSP!
