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.

For more information on how the algorithm works behind the scenes and everything else you might be interested in click on the "?" button in the creature building scene.

The most recent update has made it almost impossible to select and move joints, which is really 90% of the game once you have a decent critter built. Please see this and rebalance the sensitivity between joint and bone selection!

Great game to play around and experiment with. Only complaint is that it can be hard to process on a phone if you want to run any long simulations.

I would like to rate this game but I can't work out how to play it in portrait mode and my disabilities prevent me from playing it in landscape mode.
