SpaceChem is a puzzle game that deals with atoms and molecules.

I don't really think the story makes that much sense, but where this game really excells is in the puzzles.

The game is made up of chapters and levels. Each chapter will introduce one or two new new gameplay features. The levels take you through an easy tutorial of how to use the new element, and gets progressively more challenging. This learning curve is very good.

As for how the levels themselves work, you are given various tools and a grid. The job is to move elements (like hydrogen/carbon etc.) around, and join them to form molecules which you then pipe out. It initially seems easy but once you add mulitple reactors piping out to each other it quicky adds more of a challenge.

My only issue is, if I find myself becoming fixated on ridiculously complicated solutions. You can't skip levels if you are finding them too complicted. This means if you are completely stuck and can't progress unless you can solve each level sequentially.

This game is controlled with a mouse, but has keyboard shortcust to make things easier to control. This works really well, in my opinion.

The graphics are very simple, which is good as it makes it easy to see what exactly you're doing.

The music and sounds in this game are very nice.

There are extra challenges included once you complete the game, and ones that can earn you extras in TF2, it seems. This coupled with the wide number of challenges means the game definitely has a very good play-through time.

Definitely buy this game if you like puzzles, but don't buy it for it's chemical/scientific accuracy.

This game is one of the best games I have played. It lets you build orginal unique design concepts to finish the puzzle. Simple set of rules, many ways to get the end result.

I strongly recommend this game to someone who likes to have their brains really tested.

I'm not all that much of a puzzle person, so SpaceChem didn't hook me a whole lot. But I did enjoy what I played of it And, if you enjoy puzzle games, then I would be very surprised if you don't enjoy this game. I know a couple of people who play this game a LOT.
It has really nice music too.
I would definitely recommend SpaceChem.

SpaceChem is a genius game about "chemistry", although you do not have to know too much chemistry to play this game. Players are to design a set of instructions and algorithms for molecules to react and pass through for them to reach their output space. This game is very challenging, and you will have to search for errors, or optimize your algorithm, with given set of instructions. It is, in a sense, very similar to programming. I have spent hours playing this game because it challenged my mind and kept me thoroughly entertained. This is one of the most creative game I have ever seen and I recommend this game to anyone.

If you don't play this game I'll eat your current / future / past children.
That make a good review?
No?
Alright.


SpaceChem is a game. Gee whizz, discovery of the century.
In this game you have to mash up different elements to make new ones. Sounds simple, but some of the stuff you have to do is very puzzling and this game gets advanced, QUICK.

As well as adding elements to each other to make new ones, you also have to defend space labs and set up a network of pipes to little mini factories to merge many many elements together.

8/10, like Tetris with guns.

This game involves a lot of spatial thinking. Building tracks to manipulate molecules, and then making them more efficient. It really makes you think, and the story is actually really interesting. Chemistry is fun!

Отличная, но довольно сложная игра. Если решать задачи с МХО и параллельно играть, то получишь двойное удовольствие.
