I loved this level! But had serious troubles, finding the 532. My path here was 550, for quite some time. Then I progressed to 546, 540 and 536, where I got stuck again. I figured where I was loosing and finally managed to get that section right.
I love the way this level looks. I have a visually simmilar level in my ''drawer'' (not published), but it's a very different path, there. Maybe I'll publish, some day. :)
When JeffB set 176 I could not find it, at all. But when CarlAndre set 174, I almost immediatelly found 176 and quite soon after that the 174, too. The path is so smooth I believe it's optimal.
If not, I'll be back. :))
From the start I didn't see how to move in order to not get blocked. But after I figured that, it went quite smoothly and with each try I cut a few steps. When looking for manti's 225, I had some troubles again, but then I just jumped from 227 to 223, which was quite different.
Loved it! :))
I enjoyed looking for 551 (had a two off, before that, as well, and was stuck at 585, for quite a while).
Not sure if it's optimal. If proven not to be, I'll be back. :D
