🛼 KLOOJO
A browser-native 3D skate, graffiti and traversal game with a strict ordinary-ChatGPT core phase and a later Codex-assisted multiplayer phase. The core 3D game accumulated through sustained ordinary ChatGPT conversation. The online multiplayer implementation was later built with OpenAI Codex operating on local project files from prompt/instructions produced in ChatGPT. The complete current KLOOJO project is therefore hybrid overall.

Strict core phase → Codex multiplayer phase → hybrid overall.
Core 3D game: developed through sustained ordinary ChatGPT conversation, with the human carrying the file/runtime/testing loop.
Later multiplayer implementation: OpenAI Codex was used to work directly with local project files from prompt/instructions produced in ChatGPT.
Current classification: KLOOJO is hybrid overall. The earlier strict chat-native phase remains historically meaningful, but the multiplayer layer must not be presented as proof of a purely GPT-only implementation.
This phase boundary is documented explicitly so the public project record and the accompanying research taxonomy say the same thing.
Two players online = instant shared world.
The current multiplayer system is native to the main KLOOJO world. When two players are online, they share that world immediately rather than entering through a matchmaking screen. Remote state includes skating and tricks plus shared coins, graffiti, live names and appearance synchronization.
The broad claim is deliberately rejected.
Multiplayer games materially built with ChatGPT / GPT existed before KLOOJO, so KLOOJO does not claim to be the first GPT-built multiplayer game overall.
A prior-art search found no earlier publicly documented example matching the full KLOOJO feature combination in the searched corpus, but the multiplayer layer is Codex-assisted and therefore is not used as evidence for a purely GPT-only implementation.
This is phrased as a prior-art search result, not a mathematical claim that no obscure unpublished or undiscovered prototype ever existed.
A preserved park build plus a living public project.
Made From Chat preserves a playable KLOOJO snapshot at madefromchat.wolken.page/games/kloojo/. The current living project remains at kloojo.com, where the social multiplayer milestone was proven.
More than a skate postcard.
The local build exposes desktop and phone controls, an angular GARAGE / CREW / SWAG / CITY interface, route discovery, grinding and balancing, and a spray point that can support a broader graffiti identity than one fixed mascot.
A rotating graffiti set becomes the attraction art.
The park now uses a rotating graffiti set selected from the supplied GRAFIFTY pack, rather than constantly reusing the fox image. On the physical attraction building the graffiti sits on the side / corner of the structure like a pasted mural, not slapped dead-center.
The supplied game describes its geometry as original procedural geometry and states that it uses no commercial game assets. The full uploaded graffiti source pack is preserved locally in the archive, and a selected subset is used for rotation inside the park.
