You get a hero to play with, and you get help for what to do. You choose what code you want your hero to do and it does it. They give you examples such as:
It moves for you and you need to figure out how to move without getting caught, and how to attack them without getting caught. It's basically a adventure game, you get weapons, you look around, you go on a adventure, you attack, you basically do what an adventure game would do. But you're controlling it with codes. So I would give this 5 stars.
