It depends on your expectations really. I read some reviews and knew this game would be uber short, so I waited until it was dirt cheap and bought it. I'm a fan of the Secret Files series and this features a minor character from Secret Files 2 and is set around the same time as that game.
Considering I paid so little, the 2-3 hours it took me to beat it turned from potentially "not long enough" to "decent entertainment for little cost".
So be warned, this is a very... very short game with only three unique settings, two of which can be passed in about 10 minutes. The third location has about 5 or 6 screens in it, which you travel to and from to solve puzzles.
The best thing about this game is the puzzles are logical and not stupid. This makes the game very easy if you've played adventure games. The story actually isn't bad either for such a short game and the graphics + sound are fine.
Consider this a casual adventure to spend a few hours on and you may like it. Expect a long, fleshed out adventure game and you won't. I recommend getting it on discount or in a bundle.
