First thing in the morning

When I woke up at 8:15 a.m., the Polymatrix update was ready. I went straight to the computer, turned Claude on, and kept working on it. I installed the updated version on my phone. Some of the closed testers had taken screenshots of my game, so I did the same for them.

Later I found a bug: the beginner test level, the tutorial, didn’t actually work.

A bug only on the phone

By 9:00 p.m. I was back in the garage. Claude hadn’t fully built out the tutorial level. There was a bug on the mobile phone, but no bug when I played it in the browser. I ran it through ChatGPT to see if it could help. It was no help at all.

“It basically gave the task back to me. It said, ‘I think it’s this or this or this. Why don’t you do that? Why don’t you test this or that?’ I’m thinking, but that’s your job, man. It’s not my job to be testing code.”

So I went to DeepSeek and asked the same question, and it gave me a snippet of code to add in as a failsafe. I added it, tested it in the browser first, and it worked. Then I uploaded it to Google Console for closed testing.

Later, sitting on the outside of Lance’s bed while he fell asleep, I played Polymatrix to see what bugs the closed testers had uncovered.

Testers made the tutorial happen

The tutorial looks much better now. If it wasn’t for one tester telling me there were too many buttons and he didn’t know which ones to press, and a few other people saying the same thing, I probably wouldn’t have come up with the idea.

The tutorial is now live. The bar at the bottom of the screen with all the power-ups closes itself automatically after three seconds, and it opens again with a click, which frees up lots of space.
