will there be bigger versions of some enemies in place of some enemies of the same type? Example being a fly in the school basement being small but a 25 to 100 chance of it being bigger and stronger in both knocking down the player and more hp (2-3 hp) 2 hp if using a pistol and 3 for using melee weapon and maybe something like jock zombies and cheerleader zombies in the boss room because they are in a gym.
Good idea or not?
