[SPOILERS] I think there's more...

So I was fooling around with cheats (yeah I know i'm satan) I was giving to me the chaos card and We need to go deeper item and then I was able to get a portal from the womb 2 to the void, I know it sounds crazy and at first I thought it might be a bug, but then I notice it happened only with some characters, those being Judas, and Eve, I tried it with Azazel and Blue Baby but the portal didn't show up.

Again who knows, maybe it's a shortcut, or a weird coincidence, but I don't know.
