Very cool jam entry, especially for the other jam. Too bad you weren't really able to adapt this one at all for the LittleJS jam theme.
A tutorial section would definitely help this game a lot. It's a lot to take in to begin with, trying to get your head around all of the different UI and UX and mechanics.
Very cool audio and graphics as well. Did you do all of this music and graphics also? I'm not seeing any credits anywhere.
I'll have to give this another try to see if I can get further. I had the same experiences at most in the beginning here but will try again to leave some idle and go ahead and build houses at the beginning too!
