I am the creator of Neocolonialism, a Marxist video game in which you extract as much wealth from the world as possible. This is my first game as a full-time solo developer (I used to be a middle school teacher); I released the game in November.
It’s also Linux-native, with both a Ubuntu and distro-agnostic build. I am currently selling it on my website (subalterngames.com), IndieGameStand, and Amazon (Mac and Windows only).
