Escape Room

Controls Tap objects in the room to examine them; you can find clues (digits, order) and tools. Tap a tool in your bag to hold it, then tap an object to use the tool on it. A number lock only accepts a code after you have seen all the clues it needs. Open the hatch in the third room to escape. Your score is the number of actions used (examining, using a tool, entering a code); fewer ranks higher, so tapping useless things costs you.
