I know the full title’s longer, but for the sake of my sanity we’ll keep calling it Ouendan.

I’ve played the tutorial and the first stage. I put it on Easy and got a C. I’m still not quite sure of the timings.

Basically, it seems to be a musical manga comic strip with rhythm action stylus control. And it seems quite fun, though I haven’t seen the genius yet.

I may have to try on headphones, too.
