Themes
I didn't add too many of the optional themes due to time. Apart from it being peaceful kind of non-conflict where you are more just around the environment rather than actively playing or that it's sort of like a side quest. Maybe.

But to be honest, I started a bit late.

Tools
I tried Godot but when objects were moving there was a weird jello effect. And other things where I would spend time trying to get things to work but they wouldn't. I decided my own engine would be better programming practice anyway.

Lessons
It helped me practice writing code and that's good.
