i finished all puzzles.What will I do now?

More than you may think. For example you can make 'goals' in other words, challenging yourself on the game. You might find some more ideas reading this forum and in the VV2 guides.

watch your tribe grow... gather totems.... change their clothes...ect.

Try to reach number 1 in a certain stat (That might be a bit hard )

i tried to get tribes with all red hair, brown hair and blonde
you could also try and have goals like they mentioned in the posts above. with my last tribe i tried to get all of the pieces of the gong completed before all of my original villagers died.
or try the game on the hard setting. have fun !!

I was trying to have only 1 female and 1 male but it's reall hard. If there was 2 males I'll let him eat bad stews. LOL

Stew are very good
