Santa Slideway
A Christmas mobile game I am building end to end with AI.
The game
A runner for mobile. You fly Santa’s sleigh against the clock and deliver gifts. Every gift you pick up adds a sled to the tail behind you, like in Snake.
Five worlds, from Santa’s workshop to the northern lights. An elf thief to chase. Reindeer you collect and level up between runs. In English and Spanish.
How I build it
- AI writes all the code, in the Godot engine. I have not written a single line. I decide what to build, review it and test it.
- The artwork, the music and the sound effects are made with AI too, and so is the work in the app stores.
- The characters, Santa, the elf thief and the reindeer, are modelled and animated in Blender with AI, through a pipeline of loops: the AI builds, renders, checks the result and fixes it.
- Much of the scenery is built in code, not bought or generated.
Kite Rider, the twin
Christmas lasts a few weeks, and I did not want to show the Christmas version too early. So I released a twin first: Kite Rider, the same game with a different skin. A kid on a hang glider collects kites over a canyon, with nothing Christmassy in sight.
It went live in the browser in October 2026, so real players could test the game while Santa stayed under wraps.
Play Kite Rider ↗Key decisions
- Release a twin first, to test with real players without spoiling Christmas.
- Build many 3D models in code instead of using bought or generated ones: the download went from 14 MB to under 4 MB.
- Keep progress between runs: reindeer level up with what you collect, so a short run still counts.
