I'm sorry that you met too many monsters in catacombs. I'm glad you report this, so I can fix that.
Thank you very much for trying out the mod.
I can write a short manual. That shouldn't be a problem. Thank you
When you die, you do not become weaker all the time. You only gets reset to a box. That's how it is set.
Monster level doesn't display correctly? I'm sorry about that. I may delete that part, as it already got a bit confusing.
Monsters do scale up to your level, yes. That is to keep the player able to get exp, even though he beat the area.
They can never go above your level. They can either be the same level, or one below.
No visible specific monster in catacombs. Alright. I'll take a look at that.
Things I won't be able to fix:
Speed of battles.
Rotation of the player coming out of battles. Take a couple of seconds to look around instead.
I don't know why you couldn't open the maps. I have included everything.
Health and type is already visible. There is nothing else to show

(Yes it is very simple)
Things I will be able to fix:
Less encounters.
Creating a manual.
Fixing the small bugs.
Thank you very much for finding these things!
EDIT: Fixed, and added manual
Trying is the first step to success.
