Many more options than I initially thought. I think I found nearly all the 2-offs before seeing what to do. I found it by far the hardest of the three.
I've been trying on and off, all day long, but can't get it right. I'm currently at 134.
I think it is much more than just ''good enough''. Defence or security, whatever it is, it works tooo well! :))
EDIT (next day): I now have it at 130, with no idea where to find 2 more. I think this is a very difficult level. Will keep trying!
EDIT 2: YEEEEEY, got it! :)))
It's pending 2, atm, I hope soon two more people try it, so it can get the difficulty it deserves! !
