I was playing through the tutorial. In the part where debt display and Pay Debt are enabled, I clicked Pay Debt a few times and was confused why nothing happened. When I clicked next in the tutorial dialog, it quickly skipped through the Pay Debt dialogs leading up to the removal of the button.
I'd suggest either disabling Pay Debt until after that limiting dialog or skipping dialog ahead when Pay Debt is clicked so the dialog for each press of Pay Debt displays at the correct time.
That's the only issue I had with the tutorial!
