During preview weekend, I partied up with a couple random chums and headed down the clockworks in T1. We were in a slime level, except one that I've never been able to get back to. In that level, next to one of those branching paths that had treasure boxes at the end of it, there was like a blue notice thingymajiggy. You could access it and it was a diary from previous knights, talking about them feeding the jellies.
I didn't take a picture since I assumed they were everywhere now, but now that I think about it I have not seen a single one since. Has anyone else seen one of these or was I hallucinating?
I think there is still one of those in a level with the same sort of theme, I can't remember which. Unless I'm talking about the same level you believe is removed, though I swear I had seen it since the preview ended. However I haven't seen them anywhere else either.. would be nice to have some more to flesh out some additional story.
