Enormous wasted space aside, I really enjoyed the main challenge point of this level. I got 2-off first try but realizing how to cut those two was fun.
Finally got it. It came as suggestion for Pendings, and I was 2 off, since it came out. Since there are only ''so many'' combinations, I got it occassionally, but kind of ''brute forced''. Couldn't just evaluate by eye, which of the combinations is fastest, so I had to force them, one by one. And had unlucky order, as for what I tried first (and then next, and next ...). Probably tried the right one the last (or more or less the last, LOL).
Not sure about stars, here. Will not spoil the average. :)
