Have you ever played anything like Rainbow Tunnel? In this game you must control a ball, that is locked inside a tunnel. Start with a small speed and dodge other balls, that are considered as obstacles. Move the ball with arrow keys and step aside. Jump when you have no other options and have some fun! Avoid the black balls to go faster and increase your score!
B and S at the top left-hand corner stands for Best Score from all your attempts and S stands for your current score.
