Mate, I am not a coder. But I do have pre-Diploma in pure screen production, and almost completed my Theatre Degree many years, ago, before a parents stroke required my dropping out and returning to my country side home.... direction, stage production, and cinematography were my truly strong suits... BUT, I actually won a college award for both acting AND WRITING.
I am sure there are hundreds of people like me on here who have at least some modicum of experience with at least SOME of the elements which go in to a project like this.
I have seen other Devs actually ask for feedback proposed development pathways, or opinions on things, dedicate a thread, or page to such. So given I am sure there are many users here, even those who love your game, who could help, and perhaps make some contributions to lessen that load, ease up that headache a bit, perhaps that kind of thing you could do?
I am sure there are plenty of people who would engage with such. Now of course the downside is everyone who thinks they have the bestesr ideas evurrrr for YOUR game... but so what, you might be inundated with such BS, F'em, just take the nuggets of gold from the chaff and trash, perhaps that might be a way which helps thy aching head.
IDK, just an idea. I am sure a lot of people would hate for you burn out and abandon this project before the vision is complete. As some who loves this game so far, I for one know I would be.
