Good job on the hostile mobs but I notice you can still walk by & they won't pursue.. perhaps a roll can be made to see if they pursue or not with a notification to the player.* A rat has lost interest in pursuing you* or *A Kobald has chased you far enough & heads back to its post* well along those lines.. maybe a roll every so many feet or each section would be good. Maybe a enraged boss mob would chase you all the way through the dungeon hehe..

Maybe they can automatically hunt the player until killed for now.. advanced scripting can always be added a lot later but as it stands you can run by each mob talking one hit & they stay in the current location.
