Tethered

The Gate Keeper of the dimensions was ambushed by creatures of chaos, tearing reality in two.  Losing all his powers, he uses his last energy on creating a bond to his split selves, tethering them together.  They must heal the rifts spread across time and space, destroying the ever growing chaos. 

Fight through this dual-dimensional platformer with a friend, be careful to keep your tether intact though or you both will fade from reality.
