The team at Rustylake.com keeps producing creepy twisted room adventures.
This is the 7th game of theirs that I've played.  At the moment, they have 9 games and are working on a 10th.
In all their games, there really is no 'escape this room' objective.  Rather, solve some puzzles in the room and find out what happened or what will happen.
The main character in each game is You.  Your past/present has a history of mental illness, murder and strange hallucinations. I cruised through Cube Escape: Birthday pretty quickly.  Except for one element. I confess that I looked through Rusty Lake's walkthrough on youtube for that one tiny thing.  Then I finished the game within 5 minutes.

If you haven't played any of their games, start with Cube Escape: Arles.
