Rose & Camellia is the strangest game I've seen in a while... it's a flash game whereby anime-style women in old-European style gowns & dresses slap each other across the face (and dodge slaps!) according to movements the player makes with the mouse.
The game is available to play, there's a link at the top of the intro page to play. The first few times I tried it, it gave me a 503 error - perhaps it is too popular for the server. It loaded up eventually, though.
If you can't get it to play, you can, however, watch some of the gameplay videos on youtube.
Such a brutal fighting game... it gets hard to watch...!
