We ship a mobile game every 2 weeks with AI doing the code and the art: 5 games live on Google Play

We're a small studio (Three Lemurs) running an experiment: ship one small mobile puzzle game every two weeks (one mechanic, 500+ levels, 4 languages) using Godot 4 and AI for most of the work. Six weeks in, five games are live on Google Play:

Hedgie Queens: a logic puzzle, one hedgehog queen per colored region (527 levels)
Penguin Slide: ice-sliding puzzles (500 levels)
Paws & Yarn: unroll one line of yarn through every square, visiting the toys in order (500 levels)
Lily Hop: bring each frog to its home in as few moves as you can (500 levels)
Nekoffee: a cat café puzzle where your winnings decorate the café

How we split the work between humans and AI

Humans: the game idea, the "twist" each game needs, art direction, playtesting, and saying "no, this isn't fun."
AI for code: most of the code (puzzle engines, level generators, solvers, UI, ads/billing integration, translations) plus a lot of the boring release work (store listings, screenshots, release builds), with Claude Code.
AI for art: all the art is AI-generated. Characters, backgrounds and icons come from ChatGPT, and Kling animates the characters. A human picks, fixes and keeps each game's style consistent. It's marked as AI-generated on the store.
The rule that made it work: a single CLAUDE.md file at the repo root that acts as a living rulebook. Every time something goes wrong, the fix becomes a rule ("UI mistakes already made: do not repeat"). The AI reads it at the start of every session, so it gets better at our specific project over time instead of starting from zero.
Trust, but test: when we moved Nekoffee's level generator from a JavaScript prototype into Godot, the AI rewrote it in GDScript and wrote a test checking that both versions produce identical levels.

Lessons

Levels: generator + solver, never hand-checked. Every level is generated procedurally and validated by a solver: unique solution, solvable by logic without guessing. The AI is great at writing these; humans are needed to judge whether the result is fun.
Solvers don't catch boring patterns. In the first version of Penguin Slide, the generator kept reusing the same 4-block pinwheel trap. Every level was valid and unique, and you could solve all of them in 3 seconds once you saw the trick. Now we mix trap shapes, rotations and mirrors, and someone plays 20 levels in a row before we call a game done.
Build a shared core from game #1. Ads, billing, daily puzzle, weekly challenge, notifications, level map and the UI kit live in one core/ folder that a script syncs into every game. Each new game took a fraction of the time of the first one. The catch: a hardcoded product list in core broke the store in Nekoffee, which sells different coin packs. Shared code needs override points, not constants.
Monetize like a player, not a spreadsheet. No ads before level 10, a small coin "thank you" after every interstitial, and help (hints, lives) offered only when you're actually stuck.
Release work is a big chunk of "two weeks." Consent forms, data safety, 4-language listings, Play's edge-to-edge and large-screen warnings, review cycles. We wrote a publishing playbook so it's a checklist, not a week of surprises.

What's next: we're watching D1/D7 retention to decide which games get more love (and maybe an iOS release) and which ones we cut.
