Empty slots and the store: income, shooting, repair

Build slotsArchitectureStore items
Tap + to open Architecture. Income, attack, and repair are one menu; store items are another.

Tiles marked + open Architecture. Common groups: Basics, Earn Gold Coins, High Tech, Cool Tech, Workshop. As shown above, Broom Turret shoots, Moldy Game Console makes lightning, and Repair Bench spends lightning to fix the door.
Door stable? Build income. Entrance not dealing damage? Add a turret. Door keeps dropping and you have lightning? Consider repair. Having empty slots doesn't mean you must fill them.

Architecture spends this run's coins or lightning to place something in the room. Honey Badger Store is items, counts, and badges or ads. Both can say High Tech — don't mix them up.
Common store items:
Buy what you're missing.
Tap a building that's already down to open Upgrade. Panels often list Attack, Attack Distance, Requirement, and a price; Remove scraps it and returns some resources. A slot isn't done after you place it: drop it, upgrade from the panel, pull it if it's wrong.
