Doctor M is perhaps most famous for being part of the 4-game 'hat puzzle' (involving 3 other games from the IFComp). However, it stands well on its own.
There is a subgenre of IF consisting of games where you reflect on a life through flashbacks, and have to decide if you did the right thing or not. Tapestry, Photograph, and Map are examples.
Doctor M takes this on with panache. You have to revisit the death of three victims of you, a mercy-killing doctor. You then can choose your interpretation of the events.
There are some mild puzzles, including hunt-the-scenery and read-the -descriptions-carefully puzzles. There is one or two problems requiring a leap of intuition.
The writing was good. I believe some people said they didn't like the heavy-handedness of the moral dilemma presented in the game, but it's what's needed for this type of work.
The game has a literal angel and devil, and has 3 endings.
I enjoyed this game. I recommend it for fans of the afterlife genre.
