Should be played by everyone

I recently replayed this, this is much more than a great puzzle game. The puzzles are fantasy-chemistry based. You have an input and are given a desired output, which you reach by leading molecules through a track, that you build, along which the molecule can be altered in different ways. You do this in a grid, with building blocks that have simple functions but can be combined to reach fairly complex actions. This all leads to very fluid and satisfying chains of events when you complete your solution. To me it reaches far beyond the game by teaching you to chop up problems in smaller ones. You need to constantly switch between the problem and the bigger picture. This teaches you the value of a plan. The largest part of the challenge is knowing what needs to be done, when it needs to be done and where it needs to be done. And another valuable insight is that small alterations can have disastrous effects further down the line. This often happens when you either misjudged a problem or become over-ambitious and try to solve more as what you planned to do. All of these are things you can recognize and use all the time in day to day life. The music is fantastic; it never distracts but is still very noticeable and doesn’t get old, even after many hours in a level. The graphics are functional, go hand in hand with the gameplay, it’s really good in telling you what goes on. The learning curve felt very natural, gradually you learn more and are presented with steeper challenges. In the end you realize that you learned many things that make earlier challenges a lot more fun, so you will most likely be going back to optimize solutions. The only thing I enjoyed a little less as the rest of the game were the “end of level bosses”. These introduce an action-game element to the puzzles where you use real time commands to align your output with an enemy on screen. But, still okay, it did provide a change of pace and a sense of a conclusion to the level. 100% recommended

Love it

I absolutely love the game! I haven't finished it yet - I might take a few weeks in between puzzles. But I have definitely been up late (2 or 3am) some nights finishing a puzzle or two. I love the mechanics, you have only two waldos to work with, a limited amount of space in the reactor, and still have to come up with an efficient solution.

Unique, Genius, Rewarding

Zactronics have quite simply made something so elegant, beautiful and well designed that no-one should miss out on this. Even if puzzle games aren't your thing, this game is so unique, so challenging, and is packed with so much content, it has to be experienced. On top of probably the most clever and rewarding game mechanics in the genre. You have an amazing soundtrack. Even the story, is extremely well written and thought out. Indie gaming is saving this industry for me, and this is quite easily one of the leading examples (along with Braid, Limbo, Machinarium and Journey)
