This mobile game prototype was created as part of a university project centered around the theme of *Grimm’s Fairy Tales*. We chose to bring the story of *Brüderchen und Schwesterchen* to life in an interactive way, crafting a game where players control both siblings simultaneously. Through clever puzzle-solving, players embark on a level-based adventure, navigating challenges that test their coordination and problem-solving skills while immersing themselves in the enchanting world of the classic fairy tale.
