what is this?
A tiny multiplayer world. Every character here is a real visitor, on this page right now. Walk over and say hi, or throw a punch. Nobody gets hurt. They bounce back and blink for a moment while they cannot be hit again.
Four rooms, four games, doors at the edges. The plaza is for hanging out. The arena has a crown. Steal it, hold it, and the longest reigns go on the wall forever. The library is quiet, no punching, and typing /mark in chat writes a note on its wall that stays. The library also keeps a hangman word going, chat a single letter to guess it. The moon has low gravity and a timed run, green flag to gold flag, best times on the board.
Under the hood, your browser keeps one WebSocket open to a Cloudflare Durable Object that referees the room and checks every move, punch, and message. Physics runs in your browser. Chat is never stored. When the room is empty, the server sleeps and costs nothing.
