Some more stuff:
11. You must knock twice at the tower door.
12. You must place the chicken twice at the tower (door request 1), but door request 2, only needs to be done once.
13. All of the door request stuff only costs 1 gold for weird reasons.
14. Scrape Off Ice's description doesn't make sense. I just had to climb a mountain. What is a lake doing up there?
15. When the demon lieutenant charges at you, you get no ending text, unlike the demon assassin.
16. Reloading a save, the log on the far right is emptied.
17. Have not found a use for Wolf Pelts or Dire Wolf Pelts. If you don't go the Goblin Talk route, there is only 1 iron ore needed (for the iron sword).
18. Explore city is a weird interaction. At 3/5 uses, it reveals some actions. At 5/5, it reveals more actions. Its the only one I've found that does that outside of Gather Wood revealing Twig Creatures at 10/20 uses.
19. Sacrifice Cat says its a Major Choice, but its not under one of those "Choice" boxes, and there isn't an alternative to it.
20. Raise Zombie Cat is time consuming to do, but only offers +1 power and +1 necromancy.
21. Fetch Spring Water requires you to take Alchemist Training, even though it doesn't require Alchemy skill to do the action.
22. Create Purification Potion and Purify Spirit Tree, both take a huge amount of time to do (and the same amount of time; 45+ seconds), but don't give great rewards for doing so.
