A great game Horizon 2, Sequel of horizon but with upgraded game play. In this very enjoyable and difficult game, you will travel in the tunnel with a hyper fast ball. Collect the armor , timer and more power-ups to help you to play more. you have to be careful not to hit the obstacles in the game. You can play the game with "arrow keys" and restart it by hitting the obstacles by pressing the "space key". Have fun.
