Completed the game without collecting any treasure. No shortcuts.
You'll need to start at the Mines and make it through the entire game without picking up a single piece of treasure. Your score must not go above 0. You can accidentally pick up treasure on so many occasions. Avoid blowing up terrain as much as possible, and when you do make sure you stay away from the area because gold or gems within the terrain can fly at you. You'll have to check the ground constantly to make sure you aren't accidentally stepping over any, especially on the Jungle level. See the following video guide for more tips.
