Alien Invaders, but WEIRD!

Welcome, thanks for checking out one of my projects :) This game was made all in Java and is targeted for exploring the functionality of Java and the ability to make games with it.  Anyways the instructions can be found in the game itself, but the controls are very similar to regular Space Invaders. Although in this variation we have power-ups, one must make sure that they should only throw a punch if they can take one in this variation. Enough of me rambling on, I hope you enjoy the game and have fun!
