Lumen Mysteries

Is anyone else getting bored with the mysteries gimmick? Specifically Lumen. I'm fairly new to the indie world and I was on board for pretty much all Lumen collections. But all of a sudden now I'm feeling... Idk what the word is, but it's the same feeling you get when you eat too much of something sweet and you kind of just overindulge and feel almost nauseous and need to drink a bunch of water. That's the feeling I'm getting with them now. I got the Cthulhu collection and was so disappointed with it, I skipped the next one and will probably skip the one coming up too. They're becoming so repetitive and just meh.
