As a socialist myself, I think this game shows a lot about the problem (and the contradictions) of capitalism.
capitalism is a self-sustaining system that is incredibly unsustainable.
I looked at the small essay, and what I would suggest for you to do is to look further into socialism and communism. As lesser-known (kind of) economic systems, they might seem scary at first. However, there are a lot of leftist theory books/articles/essays on the internet, as well as, of course a great Wikipedia article and series about both of them.
I suggest reading "Why Socialism?" by Albert Einstein (yes, THAT Albert Einstein) first, as it has a spectacular critique of capitalism as well as an explanation of (one version of) socialism that would be a solution.
Monthly review still has it availible: https://monthlyreview.org/2009/05/01/why-socialism/
Hope this helps!
