Take on the role of a Reactor Engineer working for SpaceChem, the leading chemical synthesizer for frontier colonies. Construct elaborate factories to transform raw materials into valuable chemical products! Streamline your designs to meet production quotas and survive encounters with the sinister threats that plague SpaceChem.

SpaceChem is an intriguing, "problem-solving centric" puzzle game by Zachtronics Industries that combines the logic of computer programming with the scientific domain of chemistry, set in an original science fiction universe. Players build machines using mechanics similar to visual programming that assemble and transform chemical compounds. Players later connect those machines together to form complex pipelines, and ultimately construct special pipelines to fight back against space-monsters that threaten humanity. In addition to being challenging and mentally stimulating, it's been described as "one of the year's best indie games" by Rock, Paper, Shotgun, a leading PC gaming website.

More than a puzzle game

Posted on 2012-04-24 11:47:08 bycathcart's avatarcathcart:

The first thing mentioned about Spacechem is that there are innumerable ways to complete a level. And that solutions are compared according to the number of instructions used (fewer is better) and time to complete (less is better).
While these considerations are going to guide your game play, what they tend to forget is the feeling of ownership that goes way beyond simple metrics.
Youread more take pride in _your_ solution because it is uniquely _yours_, because it satisfies _your_ sense of rightness and efficiency and aesthetics. This game should be measured in terms of the emotions that it engenders, from a sense of beauty to the feeling of having created something that is the way it should be.
How many straight up puzzle games can make such a claim?

The puzzle game that destroyed me

Okay, I LOVE puzzle games. I'm not the greatest at them, but I usually fare quite well when playing entries in this varied genre (World of Goo, Braid, Wetrix+, etc...). This game has a fair difficulty curve, but becomes so wonderfully challenging. I also love that it shows you how you performed against a distribution of all Spacechem players. I the end, it's a hard puzzle game you must play if you at all like puzzles.

More than one way to skin a...

There is only one answer but it's the formulas and methods that can be your own. I really like that your results are compared to other players, there are many levels I've completed and redone to see how someone did it with fewer symbols or less cycles. Sometimes the challenge is not completion but efficiency.
