Helping folks' expectations on what is "procedural" in this submission --
This is a game built in "ZZT" (Tim Sweeney, of Epic fame's first game engine) for the "Dosember" celebration. The game randomizes the motherload-like tiles.
This is limited by the capabilities of the engine -- you observe each board "generate" live when you first load it.
Also, it fits the theme: the moon is a very cold place :)
