Update 0.2

In this update I rework the projection system , now you can use it and move the camera freely and even project to another place during the movement, also I added a new power the "shock" , when you fall from a high speed , you will create a seismic wave that will kill all the zombies and deal damage to the greater enemy. There are also a "Upgrade System" wich grant you to upgrade physic capacity or power efficiency, each upgrade require "mutation orb" wich will be give to you when you defeat a major zombies.

I also fix some bugs :
Zombies will no longer look up when you are in the air.

The character is less stuck in the ground when he uses the projection
