HAHAHA...... I saw the magic word in the subject, so I just HAD to give
this one a shot as soon as I could!
I loved it, Michael ! Excellent series of small sokobans, nicely pieced
together, and all very much their own little puzzle.
A month ago I never would have guessed I'd be saying how much I like
sokobans, but I found that creating your own, like you are doing, makes
you appreciate how they're contstructed, and how they can be solved.
I didn't have many problems with this one. Of course, I didn't get it on the
first try either,

but after a few tries on each puzzle, and remembering
what I did the first time I came through, each piece came together in the end.
A month ago, I probably would have spent hours figuring this out.
I really like your use of step on the floor boards then step off the floor
is gone too!
Very well done!
