Code Refactoring, New Enemy

Old 'totaltime' is now called 'gametime'
New 'totaltime' is the actual time in seconds since the start of the
game (without any modifiers)
New enemy 'seeker', they follow psychoball. (2 or more seekers tend to
overlap, could fix it using forces, but I'm not sure if I will, we'll
see)
Superballs can shoot any enemy

For some reason when they shoot superballs something wrong happens...
