I had tried this one once before when it had been the first song picked at start-up, and I had gotten I think two runs to the final chorus before I choked in some fashion (be it a 100/50 or a miss). This time around it didn't take more than 10 tries for the SS, so yay.
Osu! is a rhythm game based off of Osu! Tatakae! Ouendan! and the American release Elite Beat Agents. In these games you click circles to the rhythm of the song. Osu! also has different rankings you can shoot for, with SS being the best (Hit every note and have 100% accuracy). THere are also mods like Hard Rock, Hidden, Flashlight, and Double Time/Nightcore if you want to increase the difficulty even more.
