This game is quite large, taking place in 3 acts. The first act is slow, exploring a house full of arcane writings and mystical objects.
The setting turns to horror soon, as you explore a realm of evil.
The writing is uneven, with some very mundane parts and some parts (like the last few commands of part I) of brilliance.
There seemed to be some bugs. I couldn't finish the very last part of the game with the walkthrough.
