Key & Door — frequently asked questions
What makes the doors tricky?
- They are directional. A door you walked through may not let you back, so an order that collects both keys can still strand you away from the exit.
Is there an assessment mode?
- Yes. Practice mode lets you retry a board freely; assessment mode scores your first attempt, matching the real round.
