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.

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.

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.

What's new

- Stability improvements

Changes in version 4.0:
- Save recordings of your favourite simulation results in the new gallery.
- Choose skins such as googly eyes, noses, hands, feet and attach them to bones for a more personalized look. Skins are purely cosmetic and do not affect the simulation.
- Added a transform gizmo for scaling and rotating selections.
- Save file performance improvements.
- The camera now also follows the creatures vertically.
- Added a background grid for the flying task.
