Nice work but I have some requests:No idea how to change mouse sensitivity in LWJGL (you probably can't). I don't think unlimited FPS is necessary (it really eats up CPU in Slick2D, and it probably wouldn't have any benefits), but feel free to modify the source code yourself -- I can point out the few lines you'd need to change if needed. And everything is skinnable.
MouseSpeed = xx.xx
Frame Limiter = Unlimited
Skinnable Logo and Play / Exit / Download buttons :/
