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.

IMPORTANT: This is a simulator and not a game! If you are not interested in the concepts of natural selection, genetic algorithms and neural networks and watching them work together then this is probably not the app you're looking for! Everyone else, please continue reading :)

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

I want to stress again that there are no real objectives. Even if a creature of yours reaches 100% fitness, you don't win anything except for (hopefully) lots of excitement and joy.

IMPORTANT (again): The simulation is pretty CPU heavy so it will crash on most old and/or low-powered devices. If your device does not meet these minimum performance requirements you should NOT download this app!
If you just 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.

1.1 Update: You can now save and load your simulation progress.

There is also a Mac & PC version available for download and a browser version for you to try out on the main project website (keiwan.itch.io/evolution).

Ratings and reviews

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.

Tons of fun to mess with! A few tips from what I've seen in other reviews: - like real evolution, overmutation leads to failure, which is why enough iterations sometimes causes glitching. - since muscles contract and expand, adding two opposing muscles to a bone can also cause WILD glitching. The dev may want to address that if possible. - if you're geting good results after a few mutations, lower the mutation percentage so future generations are less likely to have as many wacky iterations.

This is a really well made basic evolution game, good job! Its very fun messing with nodes trying to make things that work, and its also fun bugging out the game by spamming parts. Though it would be nice to have a sort of "death selection".. What It means is being able to select parts that when you use the Evolve button and the parts selected touch the ground, the creature dies and is unable to reproduce. Just a sort of suggestion though, thanks if its added though!

What's new
