The graphic is fun and the sound can be heard.
The game guide with mouse and quiet gameplay are a relaxing change from the often stressful PS II games. The puzzles are all logically; and who does not get further times, may have recourse to the integrated in the "Diary" puzzles help.
Terrible shame is that the Secret Files: Tunguska is not a tome, but rather a Reclam book. I was a little surprised at how fast the game was over.
Nevertheless: it was fun, and the hope that the genre Adventure comes back, springs eternal.
