Codex needed one retry on the boss wave. Otherwise matches the demo exactly. Would like a step on adding music.
Mara Bell — Adding a music step to the lesson this week, thanks.

Built first time in Claude Code. The lesson is the reason I'd buy again — step 3 got me a totally different game in ten minutes.
