(11 years ago) I was also doing something wrong in the upper part :DDD Good level, confusing start and all in all, visually imposing fear on my brain. :)) 10 tries.

EDIT 2022, 14th Dec. Entered Sandman, again. Wonderful! 6 stars, not 5! :))
I wouldnt call that a problem. I often do that because I like to make my levels as hard as possible...
269/271. Just a small optimization, pretty sure I know how you got 271, which is also a good trick. Most of the level is quite linear despite the appearance, but it has some good tricks.
Well done. Good shortcuts. All the shortcuts seem designed. I was making a mistake in the upper section that always put me off about 12 moves. The only problem is the Limited movables that are used for walls. They add to the difficulty of analyzing the level visually.
