Sonic 1 Random Levels Project is a ROM hack focused on creating a Sonic 1 experience with randomly generated levels. It's a larger project compared to a simple demo. The core gameplay remains true to the original but level design, enemy placements, and potentially even object layouts are algorithmically generated, producing unique level layouts each time.  It might include an attempt at procedural generation, an advanced technique within ROM hacking. The developer is likely an independent ROM hacker.
