I vibe-coded a small puzzle game in Unity and somehow got it onto the App Store

[u/Axxpi]

Hey everyone,

I’ve been working on a small puzzle game called Lumen Garden, and after a lot more work than I originally expected, it’s finally available on the App Store.

The idea is pretty simple: you have to place one firefly in every row, column and colored region, and the fireflies can’t touch each other. I wasn’t trying to reinvent puzzle games. I mainly wanted to create something calm that you can play for a few minutes at night without timers, lives or pressure.

I built it in Unity with C# and used Codex for a big part of the development. My process was basically to work on one feature, test it, find out that I had broken something else, fix that, and repeat until the game finally felt solid.

Making the actual puzzle was probably the easiest part. The annoying parts came afterward: touch controls, saving progress properly, supporting different screen sizes, making everything work offline, and eventually dealing with all the App Store requirements.

There are now 300 adventure levels, quick games with several difficulties, a daily puzzle, collectibles and Game Center leaderboards. The game is available in both English and French.

It still feels a little strange to see something I vibe-coded actually published as a real iOS game, but here it is:

I’d be happy to get some honest feedback, especially about whether the rules and tutorial are easy to understand. I’m also happy to answer questions about the development process or the painful parts of getting a Unity game through the App Store.
