Nope, there is no building in Coaster Destroyer. The only thing you will do is letting the most popular ride in the world explore. Some dynamite is always enough.
When I say letting it explode, I really mean to devastate and turn into debris. You can choose from several types of explosives and means of destruction but some dynamite is mostly enough. The limitation is only in the “building” points and then only wait for the passengers. They make most of the points and you really need enough of them to get through the levels. Silly game but entertaining.
