Very WIP and made to test a reactive boss concept. Just wanted to
get it out here.

WASD to move, mouse to aim, shift key to shoot.

Press the "x" key to skip to 6000 HP (thats when the bossfight really
starts, up until then its to get you used to the system)

Your damage increases over how long you haven't fired and is
indicated by the radius of the red circle that follows your cursor.

If the damage is sufficient, the boss will attempt to dodge it by
speeding clockwise or anticlockwise (50/50).

NOTE: As of now, the boss is immortal and won't die on 0 HP (you will
though)
