This is a Sonic Mania Mod that Restores a bunch of Lost or changed features found in the game files and in pictures, videos, and demos, before the game was released. A TON of things have been restored/changed though it is only about 50% complete.

Ever since SM Plus Came out, it broke a lot of things that I've mostly fixed and am still working on.
