Not a very creative idea by any means for my second game. I wasn't really going for a creative game because this game started out as me just trying to learn OpenGL via LWJGL. I was originally going to make a little town game where you interacted with humans walking around, but I decided that basing a game off of an old game I made in Scratch, http://scratch.mit.edu/projects/Sammidysam/2342918
would be fun. When I discovered Slick2d, I gave up on that and decided to use Slick2d. I think I'll just use C#/C++ to learn OpenGL so that when I use Java I'm using it to make games rather than play around with OpenGL. So, as I mentioned earlier, this game is my second game - the first using OpenGL. The premise of this game is to kill the most zombies. It is very far from complete, but I have decided to share it before I rewrite most of the code. The reason behind this is because the code is REALLY bad. I really should've used methods and overrode them but I didn't, so I am planning on going back and fixing that. It will take a long time however. You can use a gun (with bullets) to kill zombies or a knife. Both are effective options. Other humans besides you can also pick up knives and guns. You move with arrow keys or WASD and point knife/gun with mouse. To shoot, you just click in the direction you want to shoot. There is no sound yet, but I'll probably add some sounds later.
Other humans move before space is pressed to start the game
