A city/world builder in a game jam is impressive! Especially one that works. Having done something like this before, I know how challenging this was.
And it works! You did a great job. I have a few criticisms, but overall everything came together:
* There didn't seem to me to be a end-state, just build until you're content? I got 999 food, money, and wood and called it a day.
* Starting the game is *rough*. I didn't know I needed to place people into the buildings to have them work, I figured the game would do that for me.
* The farms seemed to allow up to 4, but I could only place two? There was some dissonance in the UI
But, seriously, this is well done and well put together! Good work.
