Glad to hear you like it! :B

Experiences are the different game endings, once you get one you’ll see it pop up there. The demo doesn’t have that many though.

As for a guide on easter eggs, the only guide I know of it the one I’ve pinned in the Changeling Tale discord spoiler discussion channel. It has the all of the easter eggs for the full game listed, so it includes things not in the demo. They are meant to be pretty hidden, most people don’t find more than a couple in a full playthrough, so that’s a normal experience.
