This game gives me mixed feelings. On one hand, the constant hunger issue (or addiciion issue) is annoying, and the big puzzle is a "collect an enormous number of items and decipher the formula for a magic spell" puzzle, which I am terrible at.
This game is loosely based on The Raven, diverging into Lovecraft horror near the end.
On the other hand, I loved the beginning of the game, exploring, not knowing what is going on. But I lost interest about a third of the way through. I read through a transcript to see what kind of things were necessary for the rest of the game. It looked interesting, but hinges on a very difficult puzzle.
I recommend everyone at least start the game, and then see how far your interests take you.
