You wake up gasping for air in a smoke-filled bedroom. Flames dance at the edges of your vision. Through the haze, you see:

• A window with flames licking at the curtains
• A door blocked by a fallen bookshelf
• A weakened floor that groans beneath you
• An ornate safe with a numerical keypad
• A mysterious letter pinned to the wall, its edges curling in the heat
• A thick blanket on a nearby chair
• An open attic hatch above, though fire creeps upward
• A collapsible ladder under the bed, tangled in chains
• A child's half-burned drawing that looks suspiciously like a map

The smoke is thickening. Each choice matters. What's your first move?
