Want to push your limits to the limit, The World's Hardest Game is just what you need. The main character who will be at your complete disposal is the red square. He found himself in a labyrinth and its complexity does not lie in the entanglement of the moves, but in the presence of various obstacles, which will be oh so difficult to pass. At the first level, you just have to go through the field, on which small blue balls run. It seems simple, and it will be if you understand the algorithm for moving the balls. Each group moves in the same direction. If you understand this, you can plan the route and complete the level, but it still takes agility and dexterity.
