Do enemies level with the player or get stronger as time passes or anything?
There is an option "growing enemies". If it is activated, enemies become "big", "strong" and finally "mighty", depending on the number of kills of this type. It is activated by default, but you can deactivate anytime.
I've played a few times, but it seems no matter how conservative I am, forces outside of my control conspire to destroy me. Something feels unfair, as opposed to the good fair-but-merciless feeling roguelikes typically go for.
Can you give me an example? In general, surviving in LR means a lot of micromanagement, item buying/selling etc. Also, keep away from monster hives if you're not strong enough. Finally, read all the help pages.
Doesn't one of the choices at character creation mean that you aren't supposed to kill a certain type of enemy?
Yeah, Ares believers aren't allowed to kill caveworms, due to some strange religious codex. They don't get EXP for this.
The player doesn't have any way of knowing this as they make their dude.
They know it when trying to kill a caveworm as Ares-character for the first time
Two or three accidently kills won't have any negative effect.
