A one-thumb arcade game with a sharp core loop

FROSTBOUND is a frost-crystal one-thumb arcade game. You are a frozen heart at the center of an endless blizzard — tap to emit a frost pulse that shatters incoming ice shards. Destroy enemies close to your core to trigger CRYSTALLIZE, a chain-freeze effect that slows and marks nearby enemies. Features 4 enemy types (Shard, Splinter, Boulder, Prism), proximity chain combo scoring, a BLIZZARD storm event, and local high-score persistence. Ice-blue neon aesthetic on deep space.
