Early Demo Fix - 0.12

Fixes

• Fixed the game crashing when scoring a lot of points

Changes

• Took the opportunity to add exponential scaling to the overkill system, now after every 5 overkills the required points for the overkill will double
• Nerfed Mr. Bowl from base 25% to 15%, since the toys have compounding effects they were scaling a bit too fast (and also crashed the game :P )
