All of these games are inspired from The Witch's House which was the first of this kind and which remains so popular that it even got a MV remake so you might as well play this game which started it all. 😉

Actually, I finally tried The Witch's House myself and it was a waste of time because Pocket Mirror is far better, moreover I was wrong about The Witch's House being the original RPG Maker horror game which inspired all others because it was actually Ib which is not only older but also far better than The Witch's House which is merely one of the countless RPG Maker horror games inspired from Ib in 2012.
