• Tilt left and right to change the angle of the launcher and press the button to roll coins out. Basically, the coins themselves are your bullets.
• The trophies move, so shoot, shoot, shoot them before they get away. If you hit a trophy with a few shots, it will be yours.
• When you defeat formations of smaller enemies, you earn stickers and bonuses. When your green gauge fills up, it becomes possible to shoot coins rapid-fire for a short time.
• Hit the missiles to shoot them down. If a missile strikes, your coin count will decrease!
• Press the Cancel Button to quit. Then the results of your trophy and sticker shooting will appear.
• The green ones are trophies. The red ones are stickers.
• The more you play the other modes, the more coins youÂ’ll earn for the Coin Launcher. You can even earn them in Spectator mode.
