SpongeBob Krabby Patty Crisis

You must serve krabby burgers to your customers using a special burger launcher. To serve the krabby burgers to the customers, by shooting them with a shotgun, use the right and left arrow keys to move, and the space bar to fire the burgers. Change the ammo with the B key, since there are different types of patterns that you can shoot. Whatever you do, you have to shoot the hamburgers at the customers to prevent them from reaching the counter, because if they do, you lose the game, which you certainly don't want to happen.
