How to upgrade the door: level, health, coin button

Open the door panel, read level, health, and price, and tell the coin upgrade apart from the video-icon button.
The screenshot shows Iron Door LV3, 140 health, a 32-coin upgrade, and another button with a video icon. How much health you gain, and whether it fills to full, is whatever happens after you tap — look at the door after.
When you upgrade
- Note the door's level, health, coins, and lightning first.
- Open the panel and check which currency and how much.
- Only tap a button that's actually lit.
- Close the panel and see if the door really changed.
Repair Bench says it repairs the door. How fast, and how much lightning, is whatever the in-game text says.
When a ghost is close, close store windows so you can see the door and your money. Don't memorize “always keep X coins” or “upgrade after two hits.” Current health and price are more useful.
