How to continue the game after winning the Challenges

In The Binding of Isaac, there are "Challenges" that add variety to the initial Gameplay, and set the condition that you kill a certain boss (most often, it's "Mom").
After defeating a certain boss, there is not a trapdoor/womb/ ray of light that will lead to the next floor with the boss, but a winner's cup.
But sometimes you get so lucky with items that you want to continue playing, but the game itself does not allow it.
In this guide, I will tell you how to get to the next floor when the game does not allow it.

(I do not know if this bug currently exists in the Rebirth version add-ons. I'm only going through the Rebirth version right now, so I can't say for sure if this bug will work or not).

At the moment, I do not know how to get into the Dark room, Cathedral (without luck) and Chest. Now I know how to get from the Depths/Necropolis to the Womb.

You have to be either lucky or lucky here.

You will need to find a shovel ("We Need To Go Deeper!"), either in the Devil's Room or in Secret Room.

And after the victory (or before the battle with "Mom"), take advantage of it, and you will find yourself in the Womb.
The same after the victory (or the same before the battle with "Mom's Heart") You can also use it to end up in the Sheol.

The video is proof that it really works.

Thank you for reading/reviewing this guide! Even if it wasn't useful to you, it was at least interesting to you.

You know what to click and where to click.
