Robin the Mercenary:

Robin the Mercenary is the sequel to Robin the Archer. This time, Robin is equipped with a machine gun and there is new bugs and new weapons and new powerups to choose from. Collect enough coins to buy a jetpack even! Take control of this little Mercenary using the keyboard, ASDW control Robins movement, J button for jumping, K shoots, P to pause, and M mutes the sound. This game is similar to the classic mario style with the added feature of shooting the enemies. Explore each level from top to bottom collection coins that can be used to buy power-ups at the end of each level. You are given a number of hearts at the start of each level which determine your health. Each time you are hit you lose a heart, if all your hearts are gone you must restart the level.
