In the original, this was somewhat made clear by having two different colors of enemies. Red immediately came across as tougher, and they obviously were as soon as you fought them, so you knew that was a difficult area and probably not one on your current agenda.

But I thought the blue ones were tougher with few exceptions..?

oh my bad yes you're right
