It's Power Plant Act 3, but more accurate to Sonic Boom. I have the original UI from the actual hack implemented here, with the Speed counter. Oh, just so you know, that speed counter is for Sonic, not Scratch Cat. Sonic's sprite may not be the original one from the 2009 ROM hack (and the one I used is a Classic Sonic sprite and not Modern Sonic) but I don't care.
I might've been a bit late for this but whatever
