No problem! It seems others have already answered your questions better than I could, so good luck using Godot!
The only recommendation I would make is to update to a newer version if you are able to. 3 is fine, I started on it myself, but a lot of what you will find online for help is being more and more tailored to 4 and higher so it may be harder over time to get help with issues in the future.
Thank you for sharing this. I will take a look into it.
Is it actually free or is it "free" for the low low price of my private data?
