For now it's just Sonic Onset Adventure's base code, which is just SA's decompiled physics, but I have some big plans for my own fork of it. So yeah, it's real. :D
What's neat is that it's a direct re-model of the LS5E2 model I did recently just for fun. He's got some proper face control bones and ugh I'm so proud of it. Thank you for the comment. ♥
