In the game Shape Tunnel you will need to go to the three-dimensional world. Then you have to go on an exciting journey through the maze of tunnels. You have to manage the red square, which gradually picking up speed will slide on the surface. To complicate his progress in front of him there will be obstacles. In almost all of them, passages having different geometric shapes will be seen. You will need to quickly react to the appearance of obstacles and send your little square in exactly the same shape of the passage. Then he will easily pass through the barrier and continue on his way.
