Shooting Mob and Scaling Difficulty

Evening, 

I have added a rough sprite for an enemy mob that shoots that will start spawning in after 2 mins of being alive; 

Regular Mob and Shooting mob get more damage/health/speed over time and points for shooting mobs goes up over time as well, 

Adjusted where the player bullet leaves to better hit close mobs; 

Still working on having a total score (along with a few other statistics that might be nifty to see) show up in the death screen, but is a work in progress and not working right now,
