Also known as simply, "Ouendan", Osu Tatakae Ouendan is a 2005 game originally made for Nintendo's 3DS, but later got reprogrammed by some random Australian guy named Dean "peppy" Herbert. It has a storyline, had some crappy animation, but was adapted in 2007 to a PC port, where you can click with a keyboard and move your mouse.
