Layer 3 Help! (Soft Spoilers)

I'm just about to start Layer 3 when I looked at the map again and realized how much wandering around I'm gonna have to do for collecting all thebunnies.I would like to solve the puzzles myself, but the idea of looking through every single room over again to look for clues, and then spend a good amount of time in said room only to realize there weren't any clues to begin with, doesn't sound too appealing to me : /

I can accept if the intended experience is just to wander around aimlessly until you find something, but as much as I want to experience everything the game has to offer while trying to preserve the intensions of the developer, it feels like many hours of non-gameplay which isn't very fun. I've seen the Steam Traveler's Guide, but some hints for Layer 3 sort of spoil it in a way 😅. This Reddit Post seems to be better about the hints, but the origin of said hints are left out (though, perhaps, that is intentional). Is there some marriage of the two, where the locations of the hints are shown but the hints aren't completely spoiler-y?

TLDR; I want to be able to complete Layer 3 by discovering the hints themselves and where they are located rather than relying on external guides without context. Maybe the intended experience is to Google things for Layer 3 tho, idk ¯\_(ツ)_/¯ Thanks in advance!
