Together with the heroes of the game Jim's World, you will explore the world in which he lives. You have the opportunity to choose either Jim himself, whose name the world is named, or other unusual creatures that live on the platforms. To go through the level, you need to overcome a certain distance, jumping on the platforms and collecting coins. Break gold blocks to get more coins, as well as a magical mushroom, eating which the hero will grow and become a super hero. The world of Jim's World is very similar to the world of Mario. The ultimate goal of each level will be a nice castle.
