The problem

Can an AI build studio make games people return to, not demos? The bar is the best-crafted games on phones and the web.

What we built

  • Four games in one site: Cathnivore, Runnel, Hedgerow and NIGHT SHIFT, all free, all on phone and desktop.
  • An autonomous loop: an AI session every hour picks the next item, builds it, screenshots it and ships it behind eight quality gates.
  • A 3D first-person shooter with skinned enemies, armour that breaks, squad tactics, kill cams and a full district roster.
  • Shared art and a recurring heroine, Cath, drawn entirely in code.
