I Absolutely agree with SEVERAL of the suggestions and had to add my 2 cents so you knew which ones!!

Loved LOVed the idea of night and day as well as weather patterns, like raining so they go in the huts, or something. Going to sleep, and some can't sleep.

Adore the update idea, like logging on to see what has happened so and so had a baby boy, as well as month day year,season, holidays something like that. Maybe you'll have to have farmers pick more for the feast or something. winter is coming so need more huts. and so there isn't a ton of huts around maybe some get damaged with the rainy spring or something.

Blankets are cool idea for the mothers, although i do like the surprise of not knowing which is why the update screen would come in handy.

I agree with spreading out, maybe this is one part of the island and opening the cave spreads to other parts with more islanders or something, maybe a part of their tribe lost on the other side.

Tasks and chores for the kids, like master mushroom picker or something, which i why i think pets would be good, kids take care of pets and pick them out and stuff.

I really love this game. i am ABSOLUTELY addicted. i can't tell you how good you did with this game! Excellent job!
