I was stuck at 392 for ages. I was a long time unsure what to optimize: my way to bring blocks up to holes, or my way to build up the required "first step" configuration? Maybe both?
Yesterday, to eliminate that doubt, I did a testing work on how I bring blocks to holes and understood there is nothing I can optimize there.
So I started to try to think differently my way to organize blocks at start. Today, I suddenly cut 2 steps... It was the confirmation I needed to invest further efforts on that and 10 minutes later: I won!
I would like to say an enormous thank you to Alazeh, who was able to help me clarifying my ideas, that without to spoil it for me. <3
After 17 years back and forth, I finally solved this level. With it, I completed the medium world.
I'm so happy that I'm bouncing around my chair... ROFL
In my case, the 2 off wasn't due to a cut on the correct route. I was 2 off on a wrong route. And today, who knows why, I suddenly saw a new way to do it, that I had not seen before and that is - for me - totally counter intuitive.
At first, I was far away with it, but bit by bit, I came 2 off again and with a few more tries, I won.
So, for those stuck 2 off: it can very well be that you're on the wrong route. The correct one needs to be creative, and at start, gives the impression to create something too complicated and too long. But in fact, after optimization, it works.
2 years ago, I gave up on this level as I was 2 off and enable to cut the last 2 steps.
Today, I came back to it and solved it within a few tries. Now to be honest, I can see what I did different to save the 2 steps, but I don't understand why it's a saving. For me a case of "seems longer, is shorter".
** 2 years ago **
Like it, however, again 2 off, what makes me :(
** 2 years later **
I was afraid to retry working on this level. I had difficulties to return to 2 off. But once I was 2 off, I was sure where I can save 2 steps, so I worked there only and soon got it!
I find impressive the amount of different possible arrangements in the final zone in the center, leading to 2 offs and 4 offs. I needed lot of tries until finding the unique arrangement allowing for the saver.
Great level and am so happy I finally got it done.
