Your goal is to find and collect the hidden key, which is located in a different spot within each maze. You can use a map to navigate the maze and avoid obstacles. However, you'll also need to watch out for the hungry Zot's, who will try to stop you from finding the key. If you successfully recover the key without being caught, you'll unlock the next level. As you progress through the levels, the mazes become more complex and difficult, and your map will reveal less information.
