All levels in A Journey to School were designed around a shared objective: guiding both siblings to the end of the level by solving collaborative, physics-based puzzles. Players can switch between the two characters at any time, using their unique abilities to assist one another. Interactions with the environment, such as operating elevators, moving boxes, and navigating terrain, require thoughtful coordination. For example, the younger brother can activate elevators to help his sister reach higher areas, while she can place objects to create accessible paths for her brother in a wheelchair. This system reinforces themes of teamwork and mutual support while offering engaging and meaningful gameplay mechanics.
