    Due to its extreme complexity, SpaceChem will never be a title for everyone. Too deep and articulate for casual players, it will be appreciated only by those who are willing to engage themselves with the deep game mechanics Nevertheless Spece chem is no doubt one of the most brilliant puzzle game in the history of videogames.

    Chemical maniacs will definitively fall in love with this tricky and fulfilling title!

    Brain-achingly clever and hypnotically fascinating, SpaceChem is a must for any puzzle aficionado or anyone with a passing interest in programming.

    The triumph of SpaceChem is that overcoming these situations is more a case of inventing a solution than discovering one - creating a technique on your own terms that, once learned, you find yourself reusing in later stages. [Apr 2011, p.101]

    As much mental workout as excellent puzzle game, SpaceChem challenges and entertains, plus it has an engaging story.

    What I enjoy the most is the fact that there is no right way to come up with a solution. If it works, you win.

    If you like those kind of games, it's probably the best of the last 25 years. It's a game of extremes, the graphics are simply annoying, but it can keep you playing one level for a whole day.

    The level of difficulty on this game is sick! It starts out fairly easy, but it gets hard fast. Seriously, your brain will start to hurt with infinite ways to solve each puzzle as you ponder how to design a more efficient solution. One-click YouTube upload for easy solution sharing. Such a simple concept, yet so much innovation in this absolute must-have indie gem--so addicting. Expand

    Splendid puzzle game, one of a kind, definitely worth it provided that you are a puzzle gamer. The game offers a challenging and enticing learning curve, and the gameplay of continuously improving your design is definitely addicting. It is a little bit difficult and hardcore compared to most casual puzzles, but if you don't mind extracting some brain juice, you'll definitely love it. Expand

    I've been playing this before it was available on Steam. Still play it today. it's a fantastic puzzler with great mechanics and an addictive aspect of one-uping yourself and other engineers. For the guy who "looked at pictures" and decided it sucked... well, that's an obvious situation. Worth it for full price, let alone included in a Humble Bundle. Expand

    The best puzzle game I have ever played.

    The puzzles are very open ended, have many solutions, and many different obstacles and tools at your
    disposal all oriented around chemistry theme of making and breaking chemical bonds and molecules. Expand

    Awesome Challangeing puzzle game. don't worry, you won't need to know anything about chamistry to solve the puzzle.
    -1 point for an
    insufficient tutorial. If you get trouble after the tutorial learn by watching a solution or two and then you'll start to understand the game mechanics. Expand

    An amazing Sandbox Puzzle Game. It is challenging without restricting your creativity. Any solution that works is valid; you are not held to contrived expectations. However, the problems can be difficult on their own, given the tools you have available. Steep learning curve, non-trivial puzzles, and a wonderful sense of accomplishment when you make it work. The storyline is entertaining, and adds to the game. My only complaint is the music. While the soundtrack is excellent, it does not fit the mood of the game. Highly recommend this game. Expand

    From the start, this game disappointed. Entering a DRM key with extremely tiny letters into a text field with no arrow key support (you can't go back and change a letter if you get one wrong, you have to delete everything and start over) is not a good way to start a fun game. Eventually I got it working, and I soon wished I hadn't. In a nutshell, this game is too simple in the action department, and too complex in the how-to-play department. I'll admit, I enjoy a good action game, but if a puzzler is done right, I can waste plenty of hours on it. This game, however, was just too boring. I didn't care who the hero was, I didn't care why he needed to move circles (molecules) around, the game just did not motivate me to move past the first few levels. Basically, if you like dragging and dropping shapes onto other shapes, you'll like this game. And if that's the case, there's a little game with differently shaped pegs that you have to put into similarly shaped holes that you might like too. Expand
