Taken from Wikipedia:
"Machinarium is a puzzle video game developed by Amanita Design. It was released on October 16, 2009 for Microsoft Windows, Mac OS X and Linux. PC and Mac demos were made available on 30th September 2009.
Gameplay
The goal of Machinarium is to solve a series of puzzles and brain teasers. The puzzles are linked together by an overworld consisting of a traditional "point and click" adventure story. The overworld's most radical departure is that only objects within the player character's reach can be clicked on.
Machinarium is notable in that it contains no dialogue, neither spoken nor written. The game instead uses a system of animated thought bubbles.
Development
Machinarium was developed over a period of three years, by seven Czech developers, who financed the project with their own savings. The marketing budget for the game was a scant $1,000.
Reception
Machinarium won the Excellence in Visual Art award at the 12th Annual Independent Games Festival.[7] The game has received generally favorable reviews from critics, achieving a Metacritic score of 85.
