From the makers of Spacechem now comes Infinifactory. Which is basically Spacechem in three dimensions.
I played it all in 12 hours. But it's still in alpha so there's bound to be more content later. Plus there's Steam workshop levels to look forward to.
Ultimately Spacechem was a better game, but this is also very enjoyable and had a much better "story" to it as well. I would recommend it if you like this sort of thing.
