A map of where the pitfalls lead on 1F and 2F of Pandemonium.
Map
The correct pitfall to go down to continue is Pitfall 18.
This map will likely be used in the spreadsheet guide I am working on as well.
Blue lines are walls, red lines are one-way doors, and yellow stars are chests.
Thanks to Mistiry Shak for his great guide, all credit to his effort. you can also read the original guide fromĀ Steam Community. enjoy the game.
