I took a look at your document and I think it covers some really good basics concerning activism. This is something easily given to a friend or parent that has questions and mixes what is roundly recognizable as activism with things that only those within those spheres may be aware of. Then again, a person only given mainstream views of activism may see something often but not know what its called or what the function is. You made something helpful.
I do think this fits the theme. To be anti-capitalist and to take part in a game like this IS a form of activism and speaking out. It fits under the "Art" portion you spoke about, which has been around for centuries and can happen in small ways or large ones. And I believe that's important to note, or add to the contextualizing of this jam. What we are doing is activism in the form of zines, games, and art. And it is viable and relevant.
And I agree with that one person in the comments on the page - this could definitely make a good coloring book project to give out at rallies (cause coloring isn't just for kids! lol).
