Chasmancer: There was also an old, increasingly surrealistic and macabre point and click asylum adventure that I would recommend and love to replay if I could remember its name to begin with
Inkshock: Do you mean
Sanitarium?
No, I remember playing Sanitarium, it's isometric, uses sprites, and not quite messed up enough. That one was all hand-drawn, classic sideways point and click with only but few first-person scenes.
Chasmancer: and another point and click adventure about a girl offing her parents, getting locked up and trying to escape the institution, that I also can't remember the name of.
lolplatypus: If you want to replay that, too, that sounds like
Fran Bow.
Also not it, that one didn't really have any drug-induced fantastic creatures to speak of. But this one is a fairly good suggestion in its own right, and I haven't played it yet so might be even better, thank you.
