Have you ever heard of "jumphobia"? It is a fictive disease that forces you to jump whenever you find yourself on the edge of the ground or a platform. At first glance, it might seem that this is a very unpleasant disease, but you never know when it can be useful. How could such a thing ever be useful? You will have to jump through several levels and kill your enemies in them, that is why. The game also includes a level editor, where you can create your own exciting levels. Have fun.
