There was a mistake on the code of the original scene, and it was the reason of why the yellow poblation starts to grow without any reason, "_impulse" was < 0 so every time they jumped they were GAINING mass instead of losing it.

Btw, the final poblation should be really slow, at least that was my result

If you see a flashing cell, it's because it's child has an _impulse < 0 so it dies, and eaten again by it's parent
