You progress by clearing to the North, then from the entrance back to the South and up. Final mob spawns back at the entrance again. Mobs do have knockback. Collect a torch from near the entry and use it to burn books and scroll traps with a fairly annoying AOE and knockback. Also scouts should disarm the egg shaped traps. If you approach slowly you can disarm the trap without triggering it. Once it is triggered it will take a few seconds to become targetable.
