Daaamn! For a jam game, incredibly fun and addictive!
Feels like Rogue Tower mixed with Catan or Dorfromantik. Which is great, as I love all of these games.
With some work, I can easily see it becoming a commercial product I would gladly pay for, and spend hours playing.
One complaint: having to use keys to move around the map is cumbersome; it should be possible to move by holding the right mouse button, as well as by putting the cursor on the edge of the screen.
