Building an iPhone game in Unity, alone, on an 8 GB laptop: what I check before buying a world on Fab, how Claude and Claude Code split the work, the night iOS killed the game at 215 MB free, and the test gate that refuses a build with a failing scenario. Fifty-nine days of notes, with the numbers left in.

Three rejections, three weeks, one app approved. What Shopify app review actually involves for a solo builder, the setting nobody tells you about, and the bug that was hiding in the address bar the whole time.
