Underwhelming at the moment, there's just not that much to do. It seems fun in its premise, though.
It has some dangerous bugs (upgrading the church? No one can go into it until it is finished, and they will keep trying to go. All day long. Making them starve.) and weird problems (monuments often have a sizeable part underground).
Walls are free to build, which seems... too easy?
Canceling a building (or destroying one) doesn't refund the resources, which seems silly.

Anyway, good potential but I can't recommend it for 30€ in its current state.
