The turquoise box does not want to stand still, it throws it up and carries it forward along the tunnel, but various red obstacles will appear ahead and the box needs to react to them in the FASTBOX3d game, otherwise it will break. You must do this, control the left or right arrow keys, and to jump over obstacles, you need to press the space bar. All this must be done quickly and deftly, using your reaction and scoring points for each successful passage of an obstacle in FASTBOX3d. Your reflexes will be tested and you will pass it with flying colours.
