The thing that confused me was the game duplicity. It starts as a puzzle / treasure hunt, and the bits of background information seems useless and not integrated in the gameplay. The puzzles are interesting and the parser is good. The settings is a little bare, but that's the effect the author want to give.
But soon the game changes and transforms into a more plot-driven IF, with a much more deeper meaning. Still, it feels a little rushed and the message doesn't quite hit the spot.
In the end, it's a good IF, with a quite good first half and a average second half.
