i found a good glitch walk in the dessert and kill your donkey then go back and sell it for negate 900 and you can buy it back fr negative 1100 so you gain 200 each time but i personally like to trade between the huge cluster of towns at the top left hand corner you can buy alchohol for 4.2 dollars and sell for 22 dollars or buy and sell medicine yeah there pain becomes are fortune
p.s. to do this you will have to pay off the police now and then
the last ones easy put the stone tablets int he hands the click black opening/door and practise that part then put the three tablets on the three parts on the top then the bottons at the top of the next room :) enjoy retarded racist jokes
