Once again, I just can't seem to see what more you can do on this vs. on Guide 2.5. But fortunately for me, the solution for 2.5 works just as well here. :) Fun level.
Very nice pipelining level. Alas, I don't understand the nuanced differences between this and 5. They are both equally hard for me, but still good levels. Very informative.
I'm not going to lie, I honestly don't understand the difference between this and 5.5. I solved 5.5 a while before this, and when I tried this one I couldn't figure it out for the life of me. Once I finally got it, the solution that I used was exactly the same as my solution for 5.5. Regardless, this is a great pipelining level. Pipelining is magical and I need to work on understanding it better.
Incredibly abstract, beautifully interlocking, and enlightening, yet also quite approachable - this is about the most you could ask for from a puzzle. 6/5
