awww don't lose hope on the scale and scope of the game! outsource, delegate.
get a good chunk of writing and branches ahead of time, and have a willing pal plug it into the actual program. If you can get even a little pressure off having to do it ALL, let you focus on strictly art and writing (leaving godot implementing to other/s), you'd so cut time and get a workflow going. this could be something really special. I believe in you!
