Edna & Harvey : The Breakout
Trigger Warning. : Dark humor in the form of taking a jab at the insensitive treatment of the mentally ill, in understaffed and underfunded facilities. This isn't just (modern) Family Guy level poking at a bad issue; this is a Dadalic Entertainment game, and those guys are master at pushing the limits of taste, while working it inot a storyline developed enough to make it worth playing on. That said, this one isn't the darkest/edgiest of the lot, but, Daedelic stuff will often have one or more of these little forewarnings.
Edna is mentally unstable, occasioally the sorce of levity, but played painfully straight in her emotional upset at being unable to remember what she did to be in the asylum, and whither or not she even did whatever it was she is accused of. Together with her best and totally-not-imaginary friend, Harvey the Rabbit, Edna sets off to escape the Asylum, find her family, and trying to get a semblance of a real life back.
