Building something similar - using Claude API to generate mini games from text descriptions (https://codorex.com, still pretty rough).

Can confirm: Claude is weirdly good at generating functional game logic from vague prompts, but spatial precision is a constant battle. Anything involving exact pixel positions needs validation/correction layers on top.

The suggestion upthread about having it write its own measurement tools seems promising - haven't tried that approach yet.

Actually, here's a relevant example - had Claude generate an interactive solar system with circular orbits and moons: https://codorex.com/shared/yeABdJWvRHAKqHs2kxpRnZNZPWmqWSu9

Interesting that it handles this fine (functional orbital mechanics, animation) but would probably struggle to recreate the exact pixel positions of the Space Jam layout. Confirms the pattern: good at "make something like X" but bad at "recreate X exactly."
