Hello. Interesting game. Bought it, and will follow along. As I get further, I'll post further feedback here, as replies.
1) Can learn necromancy without knowing fundamentals of magic. Unlike ecomancy (from elves).
2) Wolf corpses don't count for raising zombies, as a necromancer.
3) Purifying the tree, nothing else happens after that, which I found to be odd.
4) Outside of purifying the tree, Alchemy seems unused.
5) Outside of hunting rabbits, Farming seems unused.
6) You don't need Elven language to speak to the Elves or interact with them. So not sure why its in the Library.
7) Some actions never change their duration, no matter how high your multipliers or number of times doing it. I've killed the Goblin King 5 times now, and its still 30 seconds to kill.
8) It would be nice if you had local and permanent skill progression. In that, you have a temporary skill multiplier, based on your current skill level and a permanent skill multiplier from all your loops. That way, there is value to raising skills past like level 4, in a loop.
9) It would be nice if after killing the Content Demon, that the game continued. I had 140 seconds or so till death to the Lieutenant, which got wasted when I killed the Content Demon.
10) It would be nice on the UI, if it told you what was the skill multiplier used to calculate its duration. So that you can focus on skill action development for skills related to it, to make it faster for next loop. Like I don't know what ones are affected by Precision, Animal Handling, or Speaking.

Anyway will continue playing.
