Outstanding game.

The Last Door is a very clever point-and-click, that plays with the usual boundaries of such adventure games. The graphics are gorgeous, pixels and all. The music is deep and enveloping; it works with the visual tone very well.
What makes The Last Door outstanding, is the mood that is conveyed at the meeting point of all these clever pieces.
More grim than Hitchcock, verging on Lovecraftian in tone.
Wow.
