On page 1 it says that the horn of the fawnicorn is unlocked as the reward for completing day 9. So we don't actually have complete day 10 to get the fawn...? Can someone clarify?
Also wondering if having keys in inventory will make goal 1 of day 10 autocomplete? (Planning to try to save all of day 9's keys just in case.)
Edit: Chaotarch answered that last question while I was posting. (Answer: Yes it will autocomplete)
