It’s a two-player game in which you and your friend have to go through many locations and solve riddles. Some puzzles can only be solved together, so you have to play together. Also remember to collect crystals to open the portal at the end of the location. Each player has a different colour, so some quests can only be completed by a certain player. There are also dangerous areas with both one- and two-player traps, so check every part of the location carefully.
