Remix: Leviathan

Build a small, playable browser game inspired by "Leviathan" (Action, Whale).
Concept: Leviathan is a mythic reverse-Moby-Dick action game where you play the whale, rising from the black deep to smash whaling fleets, snap harpoon lines, and free your own before the hunters close in.
Tone/hook (from the game's own page): Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls: keyboard and mouse on desktop, shown on a short how-to-play screen.
Players: single-player.
Core loop: include a visible score, an optional local high-score table, progress saved in localStorage.
Audio: add simple sound effects and music (start audio on the first click/tap).
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
