Thank you kindly for your reply and all the material!
I personally don't want to tie myself to any engine just yet, but I am thinking about making a system that would allow me to swap out code listings with more flexibility, so I could offer working code that can be written down and (mostly) work.
I have to let all this information settle down in my mind before tackling some of the sources you mentioned.
In case you have more suggestions or requests, feel free to open a topic in the "community section": https://therealpenaz91.itch.io/2dgd-f0th/community
Thank you very much.
