Developer frederik (@froessell on X) says Claude Code built most of Mowtopia, a cozy game in which players drive a small lawnmower around tiny round planets, earning coins and upgrades, in about 2 days.
frederik wrote the game up as a product requirements document split into 7 milestones, then had Claude Code build it one milestone at a time, he wrote on X. He says the result was 60 passing tests and a 15 MB web build, made in Unity 6.
All of the art is AI-generated. Seedream 5 Pro and GPT Image 2.5 produced the concepts, and Meshy turned them into every 3D model in the game, all through Magnific.
The concepts, models, an icon sheet and the audio cost about 7,010 Magnific credits on its cheapest plan. Roughly 5,240 of those credits went on the 3D models.
frederik's earlier Claude Code game, Bolt Pit: Robot Arena, is live on CrazyGames. Public numbers shared by Zeke Chan on X show 628 players, an average playtime of 3 minutes and 0.7% day-one retention.
Why it matters: breaking a game into milestones with tests is a repeatable way to keep a coding agent on track, and the credit breakdown shows what an all-AI art pipeline costs.
Caveat: the build time and costs are frederik's own figures, and AIGamer hasn't verified them.
Mowtopia is still in development, and no release date has been announced.
