Just finished it.
In general have to say the machine was good, it had different things going on and the story in general was also pretty cool.
However, I still have mixed feelings about that “jump” you have to do in order to move on. I would suggest to the people who are struggling with that bit (you know when you’re there), to actually follow the story-line that is being told through the various machines. That, along with some basic enumeration (and some simple guessing, use what you have!), can point you in the right direction.
