Concept-wise I really like this game. I love the restoration effect on the maps and the possibility of building the village as you want. My suggestions to improve the game are: 1) add a way to demolish your buildings to avoid possible locks, 2) optimize parallel process event to reduce lags and 3) implement a good save system (I guess for the jam you can't do it but it wasn't a problem for me).
Good job and keep it up!
