Spacechem

You can't just call this game a time killer, it will ruin your life, cause your pets to divorce you, and grow a sporty beard (you, not the game). I love puzzle games, and although I had never heard of the game, wondered what on earth it was, I bought it anyway. Bang goes my life! If you ever liked pipeline where you had to complete a pipe before the water flowed, you are going to adore this. It does require a bit more thought (a lot more actually) and the instructions are a little fuzzy to start with, but you soon get the idea. Build a path for the Waldo to follow and give it instructions along the way to pick up, make, break and drop molecules. the trick is never letting two molecules crash, and never allowing timing of the Waldos to stray too much. This is one of those games you keep having "just one more go", and revisitng levels to see if you can do better. I am really pleased I took the plunge on this one and seriously recommend it to anyone looking for something different.

Ok, so I love maths and machines, but this is pure beauty. You build a system which converts water and CO2 in methane and the molecules literally dance. I'll say this: it's a puzzle. It's a very fine crafted puzzle without time constraints. That's the basics, so if you like this type of games, keep reading. If not, Spacechem is not for you. The very gem of this game is his sandbox approach: except of the 'big boss' puzzle, you can do WHATEVER YOU WANT. You have some starting chemicals, and you have to manufacture some others, and for doing it you have some tools. Whatever you do with those tools is up to you. You could build a very fast process with a lot of symbols (instructions), or a very efficient one with a few symbols but quite slow. You can hack a solution inefficient and slow to advance and then revisit the old level to refine that solution with fewer symbols and less cycles. It's like the incredible machine but with the incentive of going back to rebuild your past levels in a better way. And the push to do it is presented to you after every level: a comparison with the other players in terms of reactors, symbols and cycles used. Isn't it enough? You have an entire library of custom levels to hone your skills (once you prove yourself worthy... or hack your access). If you like it, you won't run out of puzzles, that's for sure.

The only thing that let me down is the cloud save. I lost all the progess after reinstalling windows. But the fulfillment after you solve the puzzle is so wonderful, just like you try so hard to debug your program and finally it works.

All Puzzle games but this developer are good that I have played. This is challenging but very enjoyable for those who love this sort of thing.. I would recommend to those whom love puzzles and challenges and science..

Totally worth it!
