There will be a bigger update sometime in the future in which I'll try to implement some of the most requested and non-trivial features but it's going to take at least two months before I'll have time to even start working on it again.
Love this type of "ai evolution". However, the simulation is quite slow in my opinion, not graphically but the process overall. Is it possible to virtually simulate multiple creature's attempts at once instead of manually watching it advance every couple of seconds. This sort of evolution that would go as fast as the maching it is run on.
The problem is that all of the movements are simulated using Unity's physics engine. I remember that I once tried to increase the timescale in Unity but that messed up the physics simulation so the creatures weren't moving properly anymore. I'm going to try to see if there is any way I could possibly increase the overall simulation speed but I'm not too optimistic about it.
