Sphere Genetics
Simple Unity3d game as a proof of concept of genetic-based-flat-world-crawler, if you will ;).
How it works
Game is populated with random spheres. They can differ in size, speed, color, and shininess of material. Player, starting as white sphere, roams the plane and mate with other spheres. In result two new siblings are created. Each sibling has a features recalculated, randomly biased towards one of the parents. There is a small chance of minor mutation, which moves new features a little further away from parents. There is a slight chance of totally random mutation to.
How to play
Arrows to move. Space to mate. You have to be close enough to the other sphere for it to happen. Other spheres will stop when you approach. After mating, other sphere is not going to mate for some time (it is tired, you know).
