Could you add a skip turn , add one card in hand option . I think it would be better , it decreases the unluck in the game especially when you don't have any creature in hand . Otherwise 4/5 . Good music .
Very nice difficulty and to the others who complain about repairing , i found good the fact that when you are repairing the tower , she doesn't fire no more until the repair is finished .
Hee yep!
