Tiny spaces is a minimal javascript engine for building retro 2D games with AI as a core component of the game logic. It has minimal dependencies (pixi.js for graphics, and Braintrust for AI model integration) and is built to run fully in the browser.
The project contains spaced -- the game engine (basic tiling, character and leval mechanics), mapped -- a basic, in browser level editor, sprited -- a basic, in browser sprite editor, and a few demos including a minimal port of the start of Phantasy Star 1 for the Sega Master System using the original tile set.
Tiny spaces is intentionally minimal to have a very low barrier to entry, and to be as general as possible. Therefore there is no auth support, and no back end state management.
npm install
npm run dev
Point your browser at the running server (e.g. http://localhost:5173/) and click on the link called Mage. You should see a basic level, with music and no characters.
The code for mage is in src/games/mage/.
Cozy cabin is a large, detailed level. You can visit a deployed version at Cozy Cabin. The code for CozyCabin is in src/games/cozy/.
Penta is a demo game where the main character walks around a cursed town trying to figure out what is going on, and eventually remove the curse. It's largely an experiement in using LLMs as a key part of gameplay.
If you're interested in building on Tiny Spaces this is a good place to start.
