Great job finishing! I found a lot of depth to your game.
Shooting zombies as a skill doesn't carry over to investing IRL, but debt management certainly does. I wanted to include leverage as a skill in my game so you could take a loan to double your bankroll.
Loans didn't make the cut, but I did learn a lot about the difference between lending and owning. For instance, there's a pecking order when a company goes under and liquidates its assets: lenders gets paid first, then preferred stockholders, and last common stockholders. Usually the last group gets nothing, thus it's a lot riskier to own what is directly tied to the value of the company.
