Combine the ability to solve puzzles with parkour and you'll get Parkour Line map. Every stage of the map consists of several platforms placed too far away from each other to jump between them, so you need to use a special item to build a straight line, that will help you to reach to the next spot. The lines are built using a fishing rod and are active for the limited period of time.
