I'm not super far (I've had limited time to play) but I think it's tougher than the demo. I think I'm taking more damage per hit and enemies seem to take less.
Glad to hear it’s not just me. I wonder if they drop less gloom too, I had a really cohesive level 15 build at the end of the beta, felt pretty strong. Pretty much everywhere feels seriously dangerous, at level 18 even a clean shot from the bats will one shot me lol.
