How can I turn the container elements in this incremental game into buttons? [closed]

I’m trying to help a developer make their incremental game more accessible to blind users who use a screen reader like I do. The game has lots of elements that are clickable but not buttons or links or anything, so I’m trying to change them so they’re easier to navigate to with a screen reader, but the way the game has them set up makes it difficult to turn them into individual buttons. I tried and wound up turning a whole section into one big button. I know HTML and am learning JavaScript, but I think this issue is a little beyond my knowledge. It’s difficult to share blocks of code because of the setup, so here’s a link to the code.
In case it helps, you can play the game here.
Can anyone help me figure out how to change the clickable items into buttons?
