A first-person DOOM-style raycaster whose world simulation runs as SQL on MotherDuck. Each frame a SQL query casts 160 rays against DuckDoom.walls (one row per screen column); enemy billboard projection, wall-aware chase AI with line-of-sight, and shot resolution are all SQL too. React is a thin client (canvas render, minimap, HUD, render-gated WASD+Space input with grid collision) and synthesizes the E1M1 'At Doom's Gate' riff via Web Audio. Clear all demons before they kill you.

DuckDoom — DOOM raycaster running in SQL on MotherDuck

I am working on a project with MotherDuck for a Hackathon to win a mac mini. The idea I have is to have a motherduck dive be a Doom Emulator. Is this possible? I have installed the
  MotherDuck mcp server - and we want this Doom emulator in a dive to run serverside on motherduck if possible
