Magnet Rush — 3D .io Arcade Game (Three.js + Android + AdMob)

🧲 **MAGNET RUSH** is a complete, ready-to-publish 3D arcade game in the

beloved eat-to-grow genre. Players drag a chunky 3D magnet around an endless

arena, vacuuming metallic scrap into themselves while deciding what is safe

to pull — because **bombs get attracted too**.

**Gameplay**

- Move → attract → collect → grow → devour rivals → survive

- 8 procedural 3D scrap types, gold stars (+5), shields, pulsing bombs

- 7 AI rival magnets with names, levels and personalities — bigger eats smaller

- Eat-to-grow levels with XP bar, camera auto-zoom, level coin rewards

- FEVER double-point streaks, eat streaks, combo multipliers

- Live rank badge, kill feed ("Vex is DOMINATING!"), local leaderboard

**Content**

- 16 magnet skins — unique geometry each (caps, crowns, bands, frames)

- 7 unlockable map themes (industrial, neon night, desert, electric, ice,

  candy day, blossom) with full lighting/palette swaps

- Coins, high-score bonus, simulated→real rewarded ads (Revive, 2× Coins)

**Monetization & tech**

- Real AdMob: banner, interstitial, rewarded video (test IDs included —

  paste yours in one file). Web fallback simulation included.

- Saves in SQLite on native, localStorage on web. 100% synthesized audio

  (zero licensed assets). One master `Config.js` for all tuning.
