Moon card controversy possibly solved. LOOK TO LA LUNA ♥♥♥♥♥ES

[Scout Porto]

So, remember NotYourSaggitarius?
He did his own fan floors and such for Rebirth and was hired by Nicalis to work on Isaac.
Now i remember seeing a floor called ECLIPSE
As shown on a greed card.
It seems that ECLIPSE was the basis for the flooded caves, seeing as it has the exact same design, except for a missing moon.
So, this might mean we're not far off.
I can't find a single screenshot of it anymore, wich i find suspicious, as floor concepts such as TOPETH and BASILICA are still out and about on Reddit and such.
People have been speculating a way to get this new shopkeep character.
It seems awfully lazy to keep unfinished textures to a character in the game, and have those textures (or files) keep their name.
It has something to do with this super secret room in the flooded caves that seems to serve no purpose currently.
Edmund mentioned us hating mondays ( moon days) though this could very well reffer to the daily's.
I think we're very close.
