Update 1.02

Shield bug, technically not a bug, the shield was never meant to block any bullets, each point in the shield becomes a lot less worth, besides you can use the shield insta kill the splitters and it seems a waste to reduce it on a bullet.

low enemy density - Increased spawn rates, exponentials as well

Minor balancing, 1/10 chance for tank and splitter, 1/5 chance for sprinter and rest is the normal runner

Shield bug - During restart it would keep all levels of shield, fixed to not do that...
