If you were thinking of making a game following this ideology, it'd be nice to have the red pyramid symbol included, and maybe a reference to the manifesto. That's how I'm planning to do it from this point forward (I might even edit some of the earlier works to include that). I didn't think anyone else would be interested enough to use it.
I have "Trifold Manifesto by Erin Gumiho https://erin-gumiho.itch.io/the-trifold" in the back cover copy. And the red triangle works great!
