Sonic Fan Remix
From Sonic Retro
Sonic Fan Remix is a fan game currently being developed by pelikan13 and Damizean. It is a re-imagining of classic Sonic levels from Sonic 1, 2, and 3 in 2.5D detailed graphics. Initially, the game was developed on the Unity 3D engine, and later included Mercury as its programmer. After Mercury departed, in part due to frustration with the Unity platform, the game was moved to the Egg Engine by its new programmer Damizean.
