Do not forget to collect gem and shell from Lakitu. The game includes lots of upgrades that should be utilized fro better performance in the game. The graphics and the lovely set up of the game is very beautifully designed making the game play a very exciting one. Use the arrow keys to move and use the mouse to aim and shoot.
