The goal is to change the materials within the levels in order to get to the end and finish the level. It is the only way for you to get to the end. Sometimes it will be so that you can walk over deadly material and other times it will be to change the material to something that you can destroy and make an opening to get out. Collect any diamond stones that you find within a level to get a higher score. Sometimes the images will get a little fuzzy like a broken TV screen so do not play this if you have sensitive eyes.
