Doom Desert in the Decanter of Delirium

From publisher blurb: The Doom Desert in the Decanter of Delirium is an exotic OSR romp through a mysterious world of riddles, puzzles, inscrutable denizens. 5e compatible, this love letter to psychedelia is as vivid and beautiful as exciting and surreal. Get wrapped up in conversation with the dead drunks at the last saloon on earth, solve the sphinx riddle and discover the secrets of the Ziggurat, or break bread and wine with whispering harpies or the sun itself.
