A great puzzle game.
This one desrves my perfect rating.
I'm not sure I liked all the orange colouring that was used but the Cipher style was really neat. If all six ciphers had been present, by the way, that would have given us 43 diffrent locations to explore - now that would be something.
I'm kind of disappointed about how this "before it all began"-game really didn't explain anything. The teleporter is already invented, the ciphers have no explanation, there are no traces who created the submachines and you are already somewhere underground.
As usual though I like the design. I think the fourth was the best in the series as it mixed so much though the fifth was quite impressing. The one that will stay in my mind over the ages however is probably the second wich had some lovely unique designs to it, all in red - then blue, teal and yellow.
Great series, can't wait for Submachine 6 to come!
