It's text based. Runs on Linux. I worked as a programmer in my 20s but I've never made a game before and I am excited. The game is called spark

In this game you are a sprit in a creature's body and you roam through landscapes. You can become another creature by bumping into it—your spirit goes into that other body
The landforms, plant growth, and creature movements are determined by cellular automata type algorithms (this is something I've played with before). I hope to be able to make the land, plant, and creature evolution, growth, and movement reflect our reality somewhat—I hope to make them organic
The source code is public and free. It's in the very beginning stages—I'll post again here when I get to version 1.0!
