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 direction of travel. 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 to select" tool when bones + joints are near. A drop down menu with different brain suggestions "types". Add the best voted from discord.

it's a good app, fun but recently ever since they added wings and stuff it's started not actually taking the best creature, for example I made a flyer and set it for running, you'd think it would take the one who flies the farthest in either direction wich it sometimes did but more often the not even when i add the fitness penalty it takes the one who don't move

I like the game, but it has several flaws, mostly in the fact that sometimes they get into "inch wars" where the only directive is to make it farther and as some don't work as intended they will only go farther than the others and stop, which results in unproductive mutations. Also sometimes the muscles spaz out and go shooting off glitching to the top and because it got the furthest it gets that passed on, eventually it they all glitch, but other than that it's fantastic.
