I was badly stuck at 71, yesterday. Then I got directly to 2 off (in two ways). And it still took over a minute, to find the 57. Excellent!
I think the whole series is great, this one being the hardest one for me, by far.
Incredible level. Feels like Split G should be where this is currently located in the series, and let this level be the hidden final boss. So much more difficult to optimize than the other levels! I really enjoyed it.
