For me, this is the best PP1 level EVER made. It's an absolute masterpiece that has everything: incredibly clever shortcuts, dozens of tricks (and all of them different), a challenging difficulty that still never becomes frustrating, excellent use of space, and a correct implementation of backtracking (it's not simply coming back after unlocking the side of a T lock, which is the weak point of other excellent levels like "Forgive Me"; here you'll be expected to be extra careful about which blocks to push or not to push to avoid getting stuck). All in all, I think this is the peak of PP1 levelmaking, and it saddens me a bit the fact that most likely there will never be another release with this level of quality and creativity.
Very good level design. Lots of memories here. I've been stuck on this one for over a year which is the 2nd longest amount of time I've been stuck on a level. Forgive Me took me 3 years to solve while playing on and off from time to time. I've never even tried 70 and 71 up to this point. I felt like I had enough for a while and they don't look any easier.
Dear level creators: kindly stop making big levels that appear to be symmetrical, but aren't. I want to solve a puzzle, not get a microscope out to see which block is the one that's slightly different. That said, the path is pretty cool, but I can't enjoy this kind of level design.
