Evolution

About this game

Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of a neural network and a genetic algorithm can enable your creatures to "learn" and improve at their given tasks all on their own.

The tasks include running, jumping and climbing. Can you build the ultimate creature that is good at all of the tasks?

Note: If you experience some lag you might be able to improve the fps by lowering the population size in the start menu.

Ratings and reviews

2022: Creatures need to be able to set or detect orientation. Also we need to be able to zoom out more, and have more vertical viewing distance. When creating a flying creature you can't see much more than the initial viewing area preventing you from seeing a full flight. Designer needs measurement tools + multi select, arrow tool when bones + joints are near. A drop down menu with different brain suggestions "types". Add the best voted from discord.

Really cool, but I would love a game mode where the creature not only learns how to use its body, but also over time has its body change in the event the map has a wall, it would evolve, all the while chasing after food which has a hunger meter, and of course, only the survivors go on to pass down the traits, although they only have so much energy, and can only grow so much. I know that might be a lot to ask, but I wanna be able to make a simple worm, and comw back hours layer to see what I get.

AMAZING game! Fascinating! Exciting! Fun! Needs improvements! This game is wonderful, however it's lacking one or two things. You see, in real life, some creatures can fly and some can swim. I think there should be the option of wings and fins along with sky and water. Of course, the original area (for ground creatures) should be included as well. The other addition is which ways the joints can rotate, as seen in real life with knees and elbows. Other than that, amazing game!
