I just launched The only Amenity in this Endless Dungeon is a Daemonic Postal Service on Itch io!
Daemonic Postal Service is a cooperative journalling game about self-discovery, dungeon diving and making friends.
Plus it's on sale for 33% off for the first week as well.
It's a hack of Anamnesis by @goblinmixtape and inspired by my experiences playing Nethack on nethack.alt.org growing up, where other players observed your runs and sent you short messages delivered by a "Mail daemon" monster.
