wow that's kinda fast ;-)
my first game came to an end when there were no more fertile ladies. I hoped to get the 3 drifting children, but I had them once already, so only thing I could do is sit back and watch my tribe die off ...
I do drop the kids in a safe place... I mean it's not particularly on sticky spots, they just get tangled on their way to the hut
tip for upgrade: count the collectibles as soon as their picked up, not when they reach the hut...
