A daintier side of Cave
You may be familiar with Cave as one of the biggest names in modern 2D shooters. Now you can make that "modern 2D shooters and DS adventure games about waltzing princesses." Ohimesama Debut (Princess Debut) is a game about a middle-school girl who switches places with an identical-looking princess from a parallel dimension and dances with princes in her stead.
Gameplay involves moving the stylus to match a sequence of prescribed shapes, which correspond to dance moves. At the end of the performance, you'll be able to watch a replay. It seems simplistic, and it probably won't require the same amount of precision as, say, DoDonPachi, but we kind of want to see what Cave's up to with this game. Maybe they just really wanted to get in on the DS princess game wave.
