Slow down...I'll start by the first question you ask.
Tips when you first start the game:Plant the seed beside the broken machine.Get the villagers to try on the robe at the amphitheatre to determine your first Chief.This solves the first puzzle.Then,drag the chief to the food bin to create food.You can only do that per 24hrs.
Make a fire(Dry grass+wood) and get a villager to go to the place just beside the bee hive to get hom/her try out an idea.This solves the second puzzle.(600 food)
Change jobs as often as you can.You will need a few adept scientists & 3 adept builders & farmers.
Adept scientist(s): Collect the lab items scattered around the island.Most of them are vials and 1 is a cutting tool.This solves the Alchemy Lab puzzle.
3 Adept builders: This is VERY important,so read carefully.You need them to fix the machine.Drag them to the machine one at a time to fix it.Make sure that not 1 leaves the place when the others are fixing.This solves the Broken Machine puzzle.3 Masters will also do.REQUIREMENTS:Buy lvl 2 restoration.
3 adept farmers:If you're desperate for rain to get to plant a fruit, read this.Get the adept farmers to dance around the bonfire.A TRIBAL CHIEF is also needed.NOTE:Let the tribal chief dance FIRST before letting the farmers dance.You will know they suceed if you see sparkles on near them.This solves the Rain Dance puzzle.Do it the 2nd time as the tribe gets all excited celebrating that they didn't complete making the rain fall,I think.9 REQUIREMENTS: Buy lvl 2 Leadership.
Then,quicky get someone to stand on the lift.Wait till a fruit drops before dragging the villager to plant the fruit.Do it 3 times.Once all fruit trees have matured,you will solve the puzzle:"The Orchid"
This should help you start off the game.Buy a faction as soon as possible,till lvl 2 to restore fishing.A Pitcher Plant appears when you buy Nature lvl 2 and a Berry plant appears once you buy lvl 2 Magic.The recipe to get rid of the sharks are below.
For Nature:1 Pitcher Plant,2x ???
For Magic: 1 Berry Plant, 2x ???(The 2 herbs are different from the concoction of Nature)
Below will be the guide to the 2 keys(The other key,can be found at the forums/walkthrough.)
Ash Key-Sparkles will appear near the bonfire after 60hrs of burning.Let the fire go off by itself or put the fire out by dragging villagers to the waterfall.It will take a few tries.The Ash Key will remain in the fire pit as it is too hot.Do the same thing to the Ask Key-Pour water.This solves the Ash Key puzzle.
Cliff Key-A recipe is needed for this:Cactus(near the Lab),Black Orchid(At the edge of the grassy area,below the Orchard),Lotus(To the right of the Ancient Bath).The person will feel "Light and springy!" Drag him/her to the edge of the cliff(Northeast),to the right of the orchard to retreive the key.
Hope it helps! It worked for me. =)
