Dev
summary
Demos a working multiplayer Emoji game that runs locally and syncs state over websockets, using Cloud flare durable objects with partykit as the SDK; messages are explicit (player joined/left, move, game state) and winning detection is implemented server‑side. Claims that in‑memory state lives per room and that this model scales because it runs on Cloud flare are stated and shown in code, the app isn’t deployed yet but the repo and exact message types and handlers are available to inspect.
