I think this was one of RagingTsunami's top plays, which is where I got it from. Song is decently good.
What I didn't like was the random-ass lag spike I had on an SS run into the last 1/4th of the song. I shouldn't say it was "completely" random, though, since I think it was tied to someone sending me a DM. I guess. Thankfully I got this SS run either right after or a couple attempts later.
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.
There are 4,503 views in 935 videos for osu!. His channel published over 1 day worth of content for the game, roughly 21.26% of osu! content that JonathanScarlet has uploaded to YouTube.
