CORAL — One-Thumb Arcade

A bioluminescent deep-ocean one-thumb arcade game. You are a coral polyp in the abyss — tap to emit a bioluminescent pulse that destroys incoming predators. The risk/reward core: destroy enemies close to your core to charge your GLOW meter, then trigger a BLOOM burst for a full-screen clear and 2x points. Features chain combo scoring, 4 enemy types (Larvae, Puffer, Angler, Scavenger), wave escalation, and local high-score persistence.
