This is an altgame, like Depression Quest or Will Not Let Me Go, a game that seeks to bring understanding to a mental illness or other aspects of life that need awareness.
In this case, the topic at hand is social anxiety. You sign up for a haunted house tour that can result in cash prizes. Along the way, though, you encounter several social situations that cause you extreme anxiety.
The situations do seem well-designed to cause a lot of anxiety. I don't have social anxiety, but two of my close relatives do, and this really reminded me of them.
The game is fairly short, though, and I didn't get a feel that the ending was strongly connected to the rest of the game; it felt abrupt, perhaps due to the 6 hour time frame for the game? In and of itself, I thought the ending was effective, though.
Other than that, I found the game well-written, thoughtul, and interesting.
