One of my best friends is a game developer, and I helped develop this game for the Ludum Dare 36 game jam. The theme was Ancient Technology, so we reimagined No Man's Sky for the Atari 2600. He did the developing in Unity and I spent some hours on all the visuals. I took some liberties, but who cares, it was fun to do.
Go find the alien bases and travel to the center of the universe!
