Choose one node in each row, following the lines. An arrow walks you. A wall, a block or a locked door refuses the whole move.
The dotted lines in the room show where each open choice leads. Tap a node, tap the ring at the end of its line, or press that arrow key.
Some nodes are things you pick up.
- A pass. It opens one door, shown as a hollow square in the room.
- The next move goes twice as far.
- The next move slides until something stops it.
Leave through the gap. Leave with the papers, the diamond in the room, and they are a pass in hand on the next mission.
Every mission has two ways out. The tree marks the ones you have found: a dot for the plain way, a diamond for the way with the papers.
