Ciclic

Ciclic is a cyclic cellular automaton; a simulation that follows these three rules:

• Every square cell in a grid has a number from 1, to some maximum (in different colors for convenience.)
• If a cell has enough neighbors with a color 'one higher', then that cell gets turned into the higher color.
• The lowest color does the same to the highest color.

From this giant rock-paper-scissors game, structures naturally emerge. Certain numbers of colors and numbers of neighbors cause a random pile of squares to self-organize into cave-like patterns, moving spirals, and many more!

The number of colors (up to 12) and neighbors can be chosen when launching the program. The simulation can also be sped up or restarted while running.

This game is written in Godot using TileMaps, which turned out to be a very inefficient way of doing this, so the maximum running speed isn't very high.
