Sonic: Cthulhu’s Island is a fan-made platformer where you will find Sonic the Hedgehog in a dark and mysterious world inspired by H.P. Lovecraft's Cthulhu mythos. You run, jump, and spin-dash through a cursed island filled with corrupted enemies, unfamiliar terrain, and eerie environments unlike traditional Sonic zones. The game has custom sprite designs and atmospheric music that reflect the horror elements while retaining classic side-scrolling mechanics. Your goal is to collect rings, survive otherworldly hazards, and uncover the secrets hidden within the island’s depths.
