Too short, and too hard.
The gameplay itself is good, it consists of mini-games that are all controlled with the touch screen, and are either puzzles or some kind of game where you control your character. There are 4 items available at the menu. Story, the main mode of the game, is really short. Some games are actually really hard, and once you beat it, a hard mode is unlocked, making it nearly impossible. It can be frustrating to lose at most of these games, because you have to either play the same game over and over, or play all of the games to advance. Some of these games are boring, specifically the games using the mic.
Another mode is Memory, in which you play the mini-games over again and try not to die once, if you do, pffft...Game Over! This is also really frustrating, cuz' I hate playing the same level over, especially when the level wasn't all that fun to begin with.
Yet another mode is option. Not optionS, but option. It's only a language change, so...well, there is a secret, if you press a certain combination of buttons, you can record or listen to your voice.
The graphics are really good! The style is great, and it looks great.
Maniac is where you change your girlfriends outifit. You unlock clothing by beating the story in a certain amount of time, putting in a gameboy advance game to unlock an outfit, stuff like that. But, you know, I really have no intention of even playing it again, there's no reason to beat it again, but I'll keep an open mind for the sequal.
