I can say that this hack is very much surreal, I'm not joking:

Sprites and tilesets recreated to the maximum efforts and I don't know if that's intentional or not having no collision to the half-pipes but, if that's intentional, +10 points, looks more of a proto because in prototypes, various features of it are not funcional or not implemented yet. I hope that you re-create other various features from the concept arts. I hope that you make the secret zone more like it from Sonic 1 Pilot.
