Thank you very much for this feedback. I agree with many of these suggestions, and am working on adding/fixing most of them. :)
And, as for the game getting boring by the second year, that makes sense. I've avoided working on too much mid-late game stuff because I want to finish all the core systems. Which will be mostly done with this next update that's coming out soon. Otherwise, I end up breaking and/or having to remake a lot of content which really slows me down. That said, I'm hoping to focus more on the content and progression side of things in the following updates after this next one.
Thanks again!
