Best on a computer

Its worlds are drawn in a flat inked style inspired by Moebius, and the creator plans 14 temples across them. You wake in a small room and head out toward a city in the sky. It is an early build that the creator keeps updating, and it plays best with a controller.

How the creator made it

The creator says they shared a teaser after a month of work with Claude Opus 5.5 and GPT-6 Astra. They used Midjourney for visual references, made some 3D assets in Tripo or Meshy and had Claude and Astra generate others directly in Three.js. They used Suno for music. The creator turned game design principles into reusable instructions for the agents, then used them to check whether each temple teaches a mechanic, tests it and gives it a twist. They kept a visual changelog with screenshots from the running game to compare changes.
