Treasures can be found on a 2D grid, which automatons (I called them turtles) are trying to find. They use a self modifying esolang. They start out random, but the fit ones are more likely to make it to the next generation. Those which survive reproduce (with some mutations). This leads to the evolution of the source code of these turtles.

Requirements:

• Nim (1.6 line tested) and a C compiler
• only tested on linux

To run:

nim --gc:arc -d:release c main
./main
