How do you get to Gnastys Loot level without having to complete the game the right way? Because I can't be bothered to go through all the levels again just to get gems, it's really boring. I have tried the codes that are already in the cheats section but they really don't work. When you go to inventory to enter the code it dosen't do anything!!! And I did all it said, correctly. Please help me, Cheers.
