Thank you for the detailed reply!
You are absolutely correct that the current version of the game just lacks interactivity. I was too infatuated with building the systems that I didn't design an engaging experience for the actual players, something I kinda regretted now. But I suppose that's the nature of first prototypes so I will absolutely be working on this. Thank you for all the suggestions.
The UI is another beast entirely and yeah, I will be also studying up on it.
I am also interested in seeing how your game developed so let's keep in touch.
