I don't really know why I was so off at the very beginning of the song. Playing with HRHT seemed to help, I guess because I was using the lack of hd to help time the song in my head so I knew what to do when hd was back on. I guess.
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.
