Willian's Magical Pass Level 3D is an action-casual 3D platformer. Its novelty lies in offering two unique gameplay modes:
"Brawl Mode": Players select different characters and then embark on a 3D game world, slaying monsters and avoiding obstacles.
"Dual Control Mode": Players can control two characters simultaneously, switching between them at any time using the keyboard to coordinate and complete levels.
Each level in the game features a variety of monsters and bizarre obstacles, increasing the difficulty. A wide variety of power-ups are also available to help players complete the levels.
