Hahah, only animation on Newgrounds about osu! and it's actually funny, I'm rank 8k though so Lunatic Diffs are easy >:3
OMG HAHAHAHAHA THAT ENDING WAS SO PERFECT
WHAT THE LOL
I have to say it was a bit random, but very comedic. The animation was great and the sound quality was excellent. It wouldn't be a bad idea to mention a few details telling people what Osu is about, so that other people can follow the plot of this animation. Overall, you did a fine job!
