One cottage, six moments. Scroll a small 3D diorama from nightfall through first light and all four seasons. A scene to look at, not a game to play.
Moonlit Forge is not a game. It is a single scene — one small cottage with a forge beside it, sitting on a floating diorama — and you scroll through six moments of it: nightfall, first light, then spring, summer, autumn and winter. The fire in the window stays lit through all of them.
It is here because of how it was made rather than what it does. Its author, 歸藏, modelled the cottage in Blender with the help of GPT-6 Astra, imported it into a Three.js page, had the animation and interaction generated around it, and deployed the result through ChatGPT Sites — his point in posting it was that the whole pipeline, from model to deployed site, now costs almost nothing.
Treat it as a two-minute thing to look at rather than something to play. If you want an interactive piece with the same unhurried mood, Orbital Garden is the one to open next.
How to play Moonlit Forge
- Press Enter the scene and let the model load — it is a single 3D file and takes a moment.
- Scroll down. Each of the six moments has its own lighting, its own line of text and its own state of the little garden.
- The bar along the bottom jumps straight to a moment: Night, Day, Spring, Summer, Autumn, Winter.
- Pause stops the animation if you just want to look at one frame.

Why it's worth your time
The cottage is a real 3D model rather than a set of rendered images: the seasons change the same object rather than swapping pictures, which is why the light behaves consistently as you move between them.
If WebGL is unavailable or the model fails to load, the page quietly swaps in a still poster and says so instead of showing a blank canvas — one of the more graceful fallbacks in this collection.
It is also the smallest 3D piece here at around 3.5 MB, because a single Blender model compresses far better than a scene assembled out of textures.
How it was made and where it lives
Published through ChatGPT Sites (chatgpt.site) — the same hosting pipeline GPT-6 Astra uses to ship playable games straight from a prompt. The author publishes as op7418. Original: https://moonlit-forge-studio.op7418.chatgpt.site. The Play button above runs our own unmodified copy, so the game keeps working here if that page goes down — which on free hosting usually has nothing to do with the author. Nothing about the game itself is changed, and the original stays linked from every page.
ChatGPT Sites is the hosting side of the workflow OpenAI describes for building games with GPT-6 Astra: the model writes the game, then publishes it to a public address in one step. That is why so many of the newest single-file browser games are appearing on chatgpt.site domains.

The other two pieces here that are made to be looked at rather than won are Orbital Garden, an interactive particle sculpture, and RB19 Engineering Lab, which takes an F1 car apart. If you want something in this style you can actually play, Infinite Garden is the closest.
Frequently asked questions
- Is it a game?
- No. It is an interactive 3D scene with six states and no objective.
- How long does it take?
- A couple of minutes to scroll through all six moments.
- Why does it say the scene could not load?
- Your browser could not start WebGL, or the model failed. The page falls back to a still image so there is still something to see.
- What was it made with?
- The author credits GPT-6 Astra together with Blender and Three.js, published through ChatGPT Sites.
- Is Moonlit Forge free to play?
- Yes. Everything on Floating Arcade is free, with no account, ads or downloads.
- Can I embed this game on my own website?
- Yes — copy the snippet below. The embedded player links back here, which is how we ask to be credited.
