What am I missing...?
Way waaaaay down the comments, a few people have posted screenshots of their maps at 100%. Here's the first one I was able to find https://itch.io/post/7106906 Won't tell you specifically what you're missing or how to get there, but will tell you how many things there are to collect and show you the hidden rooms.
Looks like you've found a couple of the cryptids I've been trying to find, since you have one more than I've found, but are missing at least two rooms I've got on my map. I wonder where they are..
