Sonic Mania Plus Android Decomp [repack] Here
While the initial builds had some bugs and issues, the project has matured considerably. Recent "commit builds" (development versions) show that the 3D Special Stages have been optimized to run at a full 60 frames per second, and numerous softlocks (game-breaking freezes) in various levels have been resolved. The community continues to work on the Android port, with commits and fixes being made every other day, ensuring a stable and increasingly polished experience.
