In this game, players find themselves navigating a seemingly endless green tunnel, manipulating portals to reach distant platforms while avoiding obstacles and hazards. The core gameplay revolves around hopping between portals of differing colors to traverse the environment.
The main challenge lies in understanding the relationship between portal colors and their connection with hazards and platforms. Players must carefully plan their portal jumps to successfully reach the goal, all while dealing with the ever-changing tunnel layout and incoming obstacles.
