In the new game Endless Tunnel, you will go to a three-dimensional world and help a red cube travel. Your character has discovered a long tunnel and decides to explore it. After jumping into the tunnel, your cube will begin its free fall, gradually picking up speed. On the way of its movement, obstacles of various sizes will constantly arise. You use the control keys to move the cube in different directions. Thus, you will avoid collision with obstacles and get points for it.
