The gameplay revolves around switching between Alicia and Greg, utilizing their unique abilities to overcome obstacles. Alicia can transform into a witch, making her invulnerable to ice and allowing her to shrink herself, while Greg dons an imp disguise, granting him super jumping capabilities and the mastery of fire. Both characters share similar combat mechanics, requiring players to hit enemies or jump on them to defeat them.
The game features platforming and simple puzzles, with a 3D environment that follows a linear path, offering a few junction points for exploration. Players can switch between Alicia and Greg instantly, but must conserve crystals to do so, as this ability has limited uses.
