In this game you are a dog with a Batman suit and you have to collect the Kryptonite! Use your mouse to move up and down and your left mouse button to fire. You need to blow up the Kryptonite crystals and collect the remnants. Of course, that will be the easy part because they will fly right to you. The hard part will be not missing any because if you do it will affect Superman! Use the meter at the top of the screen to see his health and how far you have gone through the level.
