Ambitious entry for a game jam!
Had to restart a few times while figuring out the game in the beginning, but didn't mind and really enjoyed the exploration. However after some time I didn't know what else do except to wait. I could not figure out if there was a strategy in how to build the roads, or if it was just the positioning of the buildings that mattered.
That said I really see the potential in expanding on this, especially with different buildings having road capacities. Well done!
