PixulaAtomata (Tech Demo)

An old tech demo of mine (quite old, I just found the source in a file on a old hard drive, and recompiled it with some updating).

The game consists of different pixels that create other pixels and die based both on the pixels (or lack of pixels) surrounding them, and their individual attributes. Pixels will have similar attributes to the pixel that created them, so a sort of natural selection happens as pixels with certain attributes will create more pixels than ones that die creating few pixels, or at least that's the idea. The game and the pixels can be left to evolve by themselves, or you can create a single blank slate pixel at a location, repopulate the game with pixels, or trigger a mass extinction (there is also a roughly 0.15% chance per minute that a mass extinction will occur by itself.) The pixels interact with each other in quite a few different ways (I stole some patterns/movements from some old popular pixel simulation game rule set that I can't recall the name off), from making some sort of a oscillator to a few working together to move a long distance.

The code has been optimized, though it still might run a little slowly on older machines.
