Unlimited Resources
Enter the game's folder from your desktop and click on the \"directory\" folder in the submenu. Click on the file marked \"proto.xml.\" Look for any text that begins with the phrase \"CrateOf\" (Note: you may have to uncheck the box marked \"text only\" to edit it). In this context, you will find \"CrateOf\" before all of the items available in the game: food, wood, coin, food large, coin large. Change the number before \"CrateOf\" to whatever you like--the max number you can type is 99999.0000. You will now have unlimited access to resources throughout the game.
