Coins into lightning, lightning back into more coins

The bed makes coins, coins build a console for lightning, lightning builds mines for more coin income. Unstable door? Stop expanding.

As shown above, the Moldy Game Console costs coins and produces lightning over time. Early leftover coins can buy that second resource.

Earn Gold Coins then spends lightning on Copper, Silver, Gold, and Diamond mines for more coins per second. The line is: bed makes coins → coins make lightning → lightning grows coins.
Split spending three ways in your head: enough for one door upgrade or repair; the next building you actually mean to place; the rest as slack. Door keep dropping? Pause the loop and stabilize the door.
You can place several of each in one room and upgrade them separately. Slots are limited — don't fill the room with mines and leave the door with nothing to shoot or repair. Read Requirement on the panel before you spend.
