Thank you LDW it is a great game. I love it other than for a couple of glitches. I haven't had to use any spoilers yet and have 7 of the 16 puzzles and I think I have figured out what I need to do for a couple of more. I have 2 of the 4 collections complete. Level 2 of all techs, and at the moment over 125,000 tech points haven't decided which way to go with them yet. course another 100,000 and I will have enough to get level 3 of all of them. Really love the game. It is the best VV yet.
