A Reddit user demoed a pixel-art game world running right on ChatGPT's own website: a 37k-line userscript reads ChatGPT's answers and writes back player actions, letting you talk to NPCs, pick up items, and even dress one in a SpongeBob costume. The setting is a Halloween party murder mystery. The raw video shows how it works behind the scenes.
