Credit goes to peppy and the original osu!: https://osu.ppy.sh/ So far this is just a quick test to see if I can finally put enough time and effort into getting this tiny little thing working, and I guess it finally did. Alot of this is broken, I will attempt to fix it in the future. I know the ranking system is awful and doesn't really work, it's a place-hanger until I can be bothered to replace it with something more osu!-like that actually calculates it based on percentage and what not. I may or may not implement a song selection screen. I may or may not implement the ability to make beatmaps in-game. All hail http://wiki.scratch.mit.edu/wiki/Detecting_Clones
