Osu! Tatakae! Nodame Cantabile!
The Nintendo DS has been home to many manga/anime licenses, so it's no surprise seeing the shoujo series appear on the handheld. Judging by what we've seen so far, the game plays like a simplified version of Ouendan. Players tap a series of floating notes in time with the music, filling up a "life" gauge with each successful hit. Missing a beat depletes the gauge, ending the level when the gauge is emptied.
A flash demo of the game has been put up to promote Nodame Cantabile DS, and you don't even need to know any Japanese to play! Check it out after the post break.
