Occult Nostalgia by Achie is a dungeon crawler, role playing game made for PICO-8. At the moment, this game is a glorified tech demo, which showcases the dungeon placing mechanism with multiplayer support.
You can explore the dungeon, rescue innocent people from being sacrificial lambs and find who or what is behind all of this. Find ancient relics, defeat acolytes and monstrous beings from the other side of the veil. Can you find the magic circle and fix the seal in time, or will the cult unleash something terrible?
