Or don't buy it at all. It has an interesting mood with a touch of british sarcasm but the futher you go the worst it gets. Lazy writing and forced puzzles ruin this game. It's a Gabriel Knight wannabe at its best and a complete flunk at its worst.
This was my first time playing it and I loved it! The story was great, setting charming, puzzles logical. Acting was well beyond my expectations (even if sometimes it comes close to language lesson levels). Why only 4 stars? GoG version likes to crash and it can be very frustrating when one forgot to save because got sucked into the story.
