I love this game. I really do. It's vaguely reminiscent of Mario Party, in that it is a collection of several mini-games. There is a Falldown-like game, a fighting game, a Whack-A-Mole game, a dodgeball game, and a Space Invaders-like game. The graphics are absolutely superb. Each mini-game is hard enough that it will take you many times to beat, but addictive enough to keep you coming back for more. After you beat each difficulty level, the next level is unlocked. This game is different from most calculator games, and the novelty adds to its charm. The only wish I have is that the game wouldn't quit to the home screen when you lose... it'd be nicer to return to the main menu. Nonetheless, I would highly suggest downloading this game.
