Since most of you probably don't know, OTO2 is a rhythm action game for the DS that came out in Japan (I imported it). The game itself is pretty simple: you listen to a piece of music and tap beats, move your stylus along sliders, and spin... well, spinners along with the beat.
It all sounds fun and simple... then you try to S-rank a stage (be perfectly on beat 90% of the time). This is a video of the last stage on the hardest difficulty... no, it's not my video, but yes, I did manage to do this. The game has a replay function that lets you watch the song play out, and that's how most people upload this to youtube. It would be highly inconvenient to play the song over and over again (took me over 30 tries) with a camera right in front of you the whole time.

Hard, but crazy fun!
