Bagholder Online: a multiplayer underwater trading floor with live market data

A shared 3D room at the bottom of the sea where visitors appear as sea creatures and watch live crypto charts together.

  • The lighting follows the market: when BTC falls, the water gets darker (Twilight Zone, Midnight Zone, then the Abyss)
  • A big live price board fed by Hyperliquid perp data
  • Creature size scales with a self-declared position, and a liquidation flips the creature belly-up so it floats away
  • Node + WebSockets for presence and chat, rooms held in memory
  • No accounts, no wallet, no token

Feedback on performance, especially on phones, is very welcome.
