Wow, 2 off for a while and did not think THAT would work does match that a floppy has so small storage place I had troubles, finding the last 2 steps for 210. Very good level, IMO! Fantastic. Extremely well designed. Brutally hard. Also has an extremely misleading false path. Way easier than side A, for me. Fun one. Finally got around to this one. Masterfully crafted and elite level usage of the bidirectional block. I found this too tricky on my first set of attempts, strangely I got it nearly straight off this time. Great first puzzle.
