Ahhhh, I didn't notice that. I started to skip the enemies because I didn't think there was a need. I do understand the wish not to explain every little thing and I purposely didn't state everything in my game. I wish I had noticed that on my own. I was thinking of implementing a small "+X Time " popup but didn't get around to it, something like that when killing an enemy might be great for you and then you wouldn't have to explain it.
