Machinarium is a great buy for anyone that loved the classic point-and-click puzzle adventures from the golden age of Sierra. Dynamix, and Lucasarts.
If you are unfamiliar with adventure titles from that era, they are all share a similar formula: blend equal parts humour and puzzle mechanics, and place them into a well fleshed-out world full of interesting characters.
One of the things that attracted me to this game was it's charming art style. It's sort of like if H.R. Giger illustrated a children's book, and it lends the entire experience a very unique feel. You can tell that great care went into illustrating all of the game assets - check out the hand lettered typography on the title screen!
The narration is done entirely with visual cues, which further compliments the art direction.
There are a variety of puzzles that range from combining items, to order of operations style encounters, to traditional rubicks-cube style fare. Some puzzles suffer from issues that most solving games deal with, such as a hard to notice item - and how can you solve a puzzle when you dont have all of the tools you need?
Despite this downfall, the puzzles make a lot of sense and I never felt cheated by having to make an absurd leap of logic.
Like it's predecessors, Machinarium has a strong sense of humour and a lot of heart. The lawls tend to be delivered as visual gags, which are well served by the strong comic timing of the character animations. Even if a failed attempt at solving a puzzle isn't laugh out loud funny, it often bolsters the main character's sense of being an akward but lovable underdog.
In closing, I recommend Machinarium to anyone that is a fan of puzzles, comedy, or arts and animation. It's also a must play if you are a fan of the early adventures of Roger Wilco, or Guybrush Threepwood.
