Hi! I'm trying to make a small mobile game for myself, according to the rules of your game. However, I still haven't figured out how explosions work.
1. Do I cross out a room in the list of rooms and will not be able to build it anymore? If so, what should I do when I get to a crossed-out room in the building phase?
2. Do I cross out the icon of an already built room on the building plan, like in this video?
If so, can I cross out stairs, tower caps and observatories, etc.? If so, how does the explosion of specific rooms work?
