Thanks for the replies and help, to all. I've only been using construct for a very short time. Most of that has been creating my sprites and running animations: on a budget. Dang that's hard!
IsometricRobot, so what would the sprites look like. It's only going to be a 640 x 480 screen. No scrolling. The only movement will be left & right.
Would I make the sprites look like the background that would be visible if that part of the building were destroyed?
