Had different ways of 4 off initially. Found out that the first route that I have tried was indeed correct. I just missed the optimizations.
Although there are some fillers in this level, the 2 step savers are great!
I guess I could have beaten this in the old PP2 site but likely it was a 311 only.
I do look forward to rediscovering more PP1 levels which yfkd has taken the record! (But probably not that much for PP2, I can't do those levels with lots of holes...)
(11 years ago) Good! Seems complicated at the 1st glance, but perhaps is not so very hard. :) 5 tries for me.

EDIT 2022, 13th Oct., : rebeaten. I had troubles with getting rid of the last two steps. I knew exactly which block is causing it, but just couldn't find a way to not lose the two steps, concerning it. Then it suddenly became clear what I can do, to settle that. :))
