When the door is hit, should you switch to defense?

Watch how fast door health drops and how much money you have left, then decide whether to keep growing or save the door.

One screenshot only shows the ghost at the door and what's on the panel. Whether to switch is clearer if you watch the same door a few times: health before a hit, after one, a few seconds later, coins and lightning left.
Door dropping? Check which of upgrade, repair, and items you can actually tap. Can't afford it yet? Don't start a slow-payback building. After you tap, glance at the door to confirm it took.
Hit damage and timing change every match. Don't memorize a table.
