Gibbous - A Cthulhu Adventure is a comedy point 'n click love letter to classic-era Lucas adventures, HP Lovecraft, Hitchcock and many, many others. A lighthearted spoof of the Cthulhu Mythos, Gibbous will have you controlling 3 protagonists, dealing with strange cultists, ancient voodoo, and Dead Cthulhu himself. Well, "dead" is just a matter of opinion... Everything revolves around the dreaded Necronomicon and how it affects the protagonists' lives. Grizzled detective Don R. Ketype wants it because he always gets his man (or book); and easy going, easy living librarian Buzz Kerwan stumbles upon it and accidentally transforms his cat, Kitteh, into a talking abomination, thus setting on a quest to return her back to cathood.
