Thanks so much for reaching out! We are so glad that you enjoyed the game, and hope your longer session goes well! For secrets, both methods work though, like you, we have found that hinting at secrets through stressors does help to raise the tension and leads to bigger moves. And for Two Can Keep a Secret, a player can share any of their secrets, not just the one created from the question on their character sheet.
We would love to see the setting you created! :D
