Your colleague started writing handlers. But the handler for the .chapter element does not fire when clicking on nested .section elements. But should. Help your colleague figure it out. You just need to fix one line in the script, don’t change anything else....

I suggest creating a function checkInitCompleted that should be called from handleKeyPress once the user has enough gold to purchase the first producer....

Wow! The previous stages must have been hard. We still have some work to do, though. It’d be very useful for the user to see the current production rate of their mining empire....
