Everyone! Any player can use the moves at any time—not just the Director!
Not at all—the Director is in charge of Starting and Ending the scene. During the scene itself they should aim to facilitate: keep things moving, ask questions, and act as a tiebreaker if needed.
NOT SO EASY cards should we aim for per scene?Aim for at least one—that's for the whole group, not one for each player—though more is better! It’s hard to do “too many.”
TAKE STOCK at the start of each scene?Yep! You don’t have to if folks are naturally creating enough detail, but for most groups it’s a good idea. During the scene, SOMETHING'S NOT RIGHT is great for ratcheting up the action, but remember you can do TAKE STOCK again anytime if it feels like the scene needs more rich details to play off.
If you want to keep the game closer to 2 hours, do one scene per location. Most groups do two or three scenes per location before the Boundary, then only one scene in each of the locations afterwards. More on this here
Yes! This is automatic and happens as you go. You can quit and come back at any time without having to do anything at all (as long as you have the link or game code of course)
