Hey, great to see you make some progress with this! I definitely get not having the time though and about designing levels. I found the same issue with the little game I made recently. Level design is more of a chore than I originally thought. I mean...I think I still like creating a level that is fun but trying to come up with interesting and different levels is tough. I couldn't even imagine trying to make levels for a puzzle game. Especially since I don't really play puzzle games at all.
As for AI, yeah...when ChatGPT first blew up what...a year and half ago or so? I did use it quite a bit. More so as a crutch for programming. But I found that a lot of the time, it seemed like it didn't really know what it was talking about for specific things related to Unity. Sometimes it could at least point me in the right direction but it wasn't good enough to make entire scripts for me.
As I've grown as a programmer and feel more comfortable with troubleshooting my own problems in Unity and C#, I've been less reliant on using ChatGPT. Usually, I go to documentation and forums first before even bothering with AI.
Anyway, great work, man! Keep it up. Only way to realize the dream of full time game dev, right?
