Glad you enjoyed this one too, and found it a challenge! I was originally planning on only making the first one (for the "make a spec" mission), but I found it too easy for my liking, so I went ahead and put this one together too. I expected it to be a bit harder, but I didn't realize how hard it would be until I tried to solve it! Space constraints were my biggest issue, hence the "That shouldn't be a problem, right?" line in the description, heh.

My solution was 16/1170/22

Like the prequel, a clever idea and a nice back story that integrates perfectly into the story of the game. To me, this blocking XBus buffer puzzle, was so much more of a challenge than the previous non-blocking XBus buffer. This felt like a genuine level, far into the regular campaign of the game.
I've got it solved with a score of 13/1211/21
Very nice one, thank you for creating that puzzle.
