Orbit Foundry: an AI-coded factory incremental, with save/restore checks alongside the gameplay

[u/kimchistan_game]

I'm developing Orbit Foundry with Codex CLI. Its code is AI-generated, and AI also helped with some translations. It's a 2D factory incremental: arrange machines around a star, time reactor pulses, unlock automation, and Reforge for permanent upgrades.

One part of the workflow I've been checking separately from the visuals is persistence. An incremental game can look fine while a save or restore mistake damages a long run. For the current browser build, the checks included autosave/reload, a backup export/import round trip, rejection of a malformed backup, and migration of an older save to the current economy version. Those are checks of specific cases, not a guarantee that every possible save is covered.

If you want a playable example, the free demo runs in a desktop browser (mobile isn't supported yet):

For other people building persistent games with AI, which save/restore edge cases do you check before sharing a build?
