A good concept, kind of ripped off from death vs. monstars and laggy as hell.
It would be better if the enemies didn't spawn twenty at a time and the ability and upgrades are lacking.
it would make it more fun to have the guards killable too, it be like the same as when they find the bosses body but u could slowly kill of guards untill just the boss remained
