I agree with the above post; Don't give up! You may want to try using the tutorial, when it asks 'Do you want HELP the first time?' click yes even though you have played before. Also remember that villagers need to have enough food stored or they will starve, so make sure that you have someone with 'farming' skill checked. That way your farmer will keep foraging for food while your computer is off. Keep most of your other adults researching at the beginning of the game so you can get those tech points. The earlier you can raise your tech level in farming the better your villagers will be able to collect/store food, and the berry bush will only last so long. Mushrooms help but obviously one cannot get them unless they are actively playing the game. Maybe you can give a little more info on how far your game gets before you lose all your little people so we can offer ideas(hopefully spoiler-free)
