Most of the puzzles are dependent upon some combination of Village Tech, villager skills, and other puzzles. Although some puzzles depend upon the completion of specific puzzles, the 16 puzzles are rarely completed in the order that you see them on the puzzle screen. Pay attention to the things that your villagers are curious about and the messages that you see when you take one of your villagers ""exploring"" around the island. These often provide clues that will help you solve the puzzles. Another good strategy is to drag one of your adult villagers around the island after every tech purchase and look for new things that they can work on. It takes time for your villagers to gain the necessary skills and technology to work through all of the puzzles. The berry supply is limited and you'll need to find another food source as soon as possible. Nursing mothers devote all of their time to caring for their baby and don't do any productive work in the village for 2 years of game time. Babies eat as much as adults and making too many babies too soon can quickly create a food crisis. The villagers need to be taught to perform a job - they will not initiate tasks in an occupation in which they have no skill. Your villagers will not produce babies if there is not enough housing. Any villager (even a sick one) can heal another villager, but healing is only possible when a villager's status is ""Sick"" (check the Details screen). Sometimes a villager will ""resist"" healing attempts by a specific doctor. If that happens, try to heal your sick villager again with a different villager. Picking up a villager while they're working will interrupt them, and they will drop the object that they were carrying. The children can find and harvest a certain kind of food.
