I was working on the project by myself in VS Code and, along with the demo, committed the entire source code on release. Future development will, of course, be used with version control. I'm also sharpening my version control skills.
I had simply done some quick changes with the web UI for language (and also to add more demo images later).
Not sure how this is correlated to the actual product though.
Unsolicited advice: Stop using the Github web UI asap. It will slow you down. VScode has git integration. There's an upfront cost to learning it but it's worth it.
If you're willing to take the plunge it's best to use the git command-line interface directly. It pays in the long run. But I understand it's kind of daunting at first.
Whatever you decide, whether its VScode or the git CLI, just get off of the Github web UI. Trust me. I look at my old projects from when I was in high school and I deeply regret that I didn't do version control. So much information that gets lost.
