This is a mock-up image. This is not a game and will probably not represent the full game. Funk Factory is at the base of the mountain and has lots of music gimmicks. I've decided to put both Time Attack colours and normal ones in this project.
The music comes from Sonic - After the Sequel and Ear- I mean Earthworm Jim. The background comes from Stardust Speedway in Sonic Mania. Most of the ideas here are from/inspired by Sonic Advance 2's Music Plant, Chemical Plant, and Metallic Madness.
