Explore all the settings and get items that help you throughout your adventure, such as gold, potions, weapons, etc. You can also talk with the people who live in the town, who give great tips. Go deep into the cave and fight with all types of creatures.
Depending on the achievements you get, you can gain experience for Claudius and Laila, who are the two main characters in the story, at least for now. If you win combats, you'll also learn new skills, and increase your health points too.
