This is a fairly hefty Quest game in Bitter Karella's characteristic style: goofy characters, classic TAKE/DROP/LOOK gameplay, vivid settings.
You play as a "level 2 succubus" from the pits of tartarus, trying to find your mother who has been kidnapped by nuns.
The twist to this game is that you can possess all of the characters, each granting you different abilities and sometimes even changing the appearance of the game itself.
Quest always has some problems that make it not quite as responsive as inform, but Bitter Karella handles it well. I strongly recommend downloading for offline play, as the servers can get tied up.
