Thanks for the compliments !
Speaking of sound (noise), yes it's true it's annoying. It was a wrong choice.
The beep means that the population is dying out. The sound is reproduced when the number of males or females falls below a certain threshold. At this point, a creature with random genes is added.
If you put the turbo and minimize the window the program should run much faster.
In theory, after a long simulation, the population should no longer risk extinction, and therefore should no longer hear the sound.
Maybe I will remove it in a future update.
