Gotchiverse 2D

Not every multiplayer world needs an engine build. A 2D world delivered as a web application loads instantly, deploys like a website, and skips the WebGL download entirely — but it still needs authoritative server state, or players desync the moment two of them interact.

The client is a fork of the Aavegotchi organisation's Next.js and React application, with Phaser handling rendering and input, so the game ships as an ordinary web deployment. My work was the multiplayer half: an authoritative Colyseus realm server written from scratch, owning movement and world state, plus the client-side netcode integration against it. The transport is switchable by environment variable so the client can still run standalone. Shared game data is vendored so both halves agree on the same definitions, and the two deploy independently — client on Vercel, realm server on its own host.

Live at gotchiverse-2d.xyz with a walkable multiplayer world. The realm server is an original build; the client is a fork of the upstream Aavegotchi project carrying the netcode integration.
