I don't really have a lot to say about this one. I basically just downloaded it because it was the most recent song to be ranked that day/night, and SS'd it within a couple of tries. Finding bullshit aside, it kinda makes the point that my consistent SS floor is right at 3.4*'s or so now.
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.
