If anyone feels like importing a game, I've got one to recommend: Umihara Kawase Shun Second Edition Kanzenban (Shun is sometimes written as Jun, but that's incorrect).
If you're not familiar with the series, this is Umihara Kawase, and this is Umihara Kawase Shun. Not much to say about them; the videos pretty much cover it.
Neither game was released outside Japan. There was a PSP port of Shun, but it had some pretty serious bugs in the physics engine. Naturally, that's the one version being translated (supposedly - they're sure taking their time with it).
So now there's a DS port of both games. Just got it the other day, and I can confirm that this one's actually good. I'd highly recommend it to anyone who might be interested.
