Demolish

See this building in front of you? It should be demolished and you are the very person in charge of it! Your task is to bring the structure to the ground using as little resources as possible. You’ll have a certain supply of mechanisms and explosives that you can resort to, but note that their amount is limited and you shouldn’t waste all of them right away. Sometimes it will be enough to make one apt shot from a catapult and the building will collapse. But on later levels, there are much more complicated challenges waiting for you!
