That One (Cancelled) Sonic FNF Mod

Game description:

Sonic is a character that doesn’t require an introduction. Everybody knows this super speedy blue hedgehog, even those who never watched the cartoon or played the video games. And now he is about to make another appearance in another great FNF mod. Once again you will clash with Sonic on the neon-lit stage singing groovy songs and trying to keep up with the beat. Watch the arrows on the screen very closely – they are going to let you know which buttons to press right now!
