Do jackals only appear after you've killed every enemy in the level? I don't recall one ever spawning before I've cleared a level of screamers, haters, tubers, etc before.
Its like the Ghost in Spelunky. The Jackals are the game's way of making you hurry the fuck up. If you take too long on a map you'll hear an alarm go off and then one of the jackals will appear with more appearing the longer you stay on the floor.
