Thank you :)
I thought the debt system was simple but maybe I should’ve explained it;
With every block that appears on the conveyor, your debt increases by 1.
If you complete all the items in the list, your debt decreases.
If you throw a block into the incinerator, your debt decreases.
If your debt fills up, you lose.
The game becomes about finding the right balance of giving and taking blocks to keep your debt in check.
Hope that helps!
