Thank you so much for your kind words! I’m really glad to hear that the game is resonating with you :-)
To answer your questions:
By default, the Time Limit has a minimum of 6, meaning there are no Random Events at Default difficulty. However, the Time Limit can go lower at Easy difficulty. That said, you were absolutely right about there being a typo in the Scene Event table. I’ve fixed it and adjusted the table so that Random Events can occur at Default difficulty.
The updated PDF is already available for download.
Regarding moves in PbtA: unless otherwise stated (like with the Investigate move, which can happen only once per scene), there are no limitations on how many moves you can play in a scene. You can make as many as the narrative allows.
Thank you for your feedback, and I hope you continue enjoying the game ;-)
