A blue dog has appeared in the monochrome world of the game Challenging Track. He is looking for an owner, but he doesn’t want to live in such a boring, monotonous black and white world. Therefore, the dog decided to go through the world and move on. But it turned out to be not so simple. You will have to move from one door to another. In this case, you need to find the white keys in order for the door to open. Tough parkour on platforms awaits you, and with each new level the track becomes even more difficult. However, the hero is not discouraged and is not going to give up his goal, and you must help him with this in Challenging Track.
