As a freeware this is a must have for every gamer in the world.
The puzzles for the most part are quite logical and there aren't any pixel based searches as there were in the old days. Graphics is also nice and it works. And the gameplay is satisfyingly easy. Voice acting is done well which cannot be said for most of the games with character audio.
But by far the best part in this game is the humour whether in the puzzles or in the dialogue or in the game in general. They're just hilarious. I like games with a sense of humour and this one clearly has it. My advice: Get yours today! With these prices it's a real bargain.
