Call Of The Abyss

Build a small, playable browser game inspired by "Call Of The Abyss" (Action, Shooter, Wave-defence).
Concept: Play as the last crab on a sun-bleached beach, holding the line against endless waves of mutant sea creatures with water-powered weapons until Cthulhu himself rises from the abyss to end you.
Tone/hook (from the game's own page): Call Of The Abyss: a wave-defense shooter where a lone crab holds the beach against the rising tide of the deep. Built for Vibe Jam 2026.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): mouse to aim or look, click to shoot/attack, Space to jump, Shift to sprint/dash. Show them on a short how-to-play screen.
Players: single-player.
Core loop: include a timer or round clock, levels, stages or waves that ramp up, an optional local high-score table.
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.
