Diagonal is a controlled puzzle game, and the goal in this game is to control the bullet to avoid squares and other rockets that can destroy the bullet. But you need to remember that bullets can move only diagonal. It is hard to control but in another way, it is interesting and funny. When you get the catch it will be easy for you to play. Collect the blue balls that will be on your way and try to play longer as you can without crashing, or being hit by some rocket. Enjoy playing this game here at Y8.com!
