Tap a glowing door on the plan, tap Open the door, then pick 1 of the room cards to put behind it. Each room you step into costs a step. When the steps run out, dawn comes: your notebook, the day count and your upgrades stay. In the game, More > How to play explains every rule.
No. Every door offers at least one room that keeps a way forward open and keeps the orrery in reach; those cards carry an arrow mark. A room your notebook points to starts showing up the day after you find its clue and is sure to be offered within two days.
The first 3 in-game days, with every rule, the notebook and dawn. One payment unlocks every day after that. No subscription and no ads.
