I played through a game of this solo after a friend of mine did the same themself, using it as a tool to explore
one of my characters'...well, character. Not sure if it was healing or cathartic per se but
I did cry quite a bit over the course of the 20 (in game)
days. Also, reached 0 on the absolute final day and wasn't sure what to
do, so I left it up to a coin flip.
The setting is very intriguing and leaves a lot of room for creative interpretation, making for vastly different experiences of what's ultimately the same setup.
The free-form nature of it makes for a very lonely and yet compelling solo experience- haven't played it with anyone else yet so I'm unsure of how it is in collaboration, but as a solo ttrpg it definitely plays well.
I highly recommended you check it out if you're interested in psychological horror (or even if you enjoy character analysis in surreal apocalyptic settings).
Neat puzzle game! Very abstract spatial reasoning. quite straightforward.
