2 viewpoints: M/C in the Escape Room, Family waiting
Plot: M/C trapped in an Escape Room, has to solve many different puzzles to get out. The solution of each puzzle has a bearing on the next puzzle. The Escape Room and its puzzles are actually all in the M/C's mind because they are in a coma after an accident. The 2nd viewpoint is the family and doctors seeing small progressions as each puzzle is solved in the M/C's mind: waking up from the coma but non-interactive, physical twitches as motor-control functions start to come back, real-world recognitions, speech-recovery, etc. The Escape Room is a mental prison of sorts for M/C's bodily control, personality, and memories.
