TikTik - Collaborative Puzzle Game
●ValidatedPlatform: Unity · English, French · · verified 63d ago
Description
TikTik is an online, puzzle game developed for Dr. Cvetomir Dimov at the University of Geneva to study individual and collaborative problem-solving. In the game, players must work together to navigate two characters, an ice cube and a fire ball, to their respective target locations. The characters' paths are obstructed by a series of fire and ice rays that carve the game board into isolated regions. While characters can move freely within their current region, they cannot cross between them alone due to strict movement rules: the ice cube can pass safely through ice rays but is instantly destroyed by fire rays, while the converse is true for the fire ball. Because characters cannot cross opposing rays on their own, the core problem-solving mechanic relies heavily on teamwork. A character can block a ray of its matching element, cutting off the ray in its direction of flow and effectively opening a safe path for the other character to pass through. To succeed, players must collaborate to discover the correct sequence of these ray-blockings that ensures that both characters safely reach their targets.
