Excellent! I just went back and replayed 1 and 2 from the olden days and then found how many more there were. This was the first of the Submachines that I had not yet played before now.
There is no doubt that this was the simplest of the first three, but there were a couple of healthy challenges... just nothing that made you really have to sit and breathe. I liked the last one (the one that... *cough*... ends the game).
Although I'm confused as to why people are taking off points for ease when they're still looking at walkthroughs.
