When kiki replied in Tinyban thread, that the button puzzle is "nothing compared to Travoltaban", OF COURSE I downloaded the Travoltaban, to find out a tough sokoban challenge.
The box puzzle was quite challenging.

Middle difficult, I think. But still not very hard. And I'm even a not-so-good sokobaner, will convert someone's SUPASOKA in Wonderland... abandon all hope, ye who tries to solve supasoka!

On infordigital.com there is someone named Paulo Matoso. HE is a real good sokobaner.
Oops -- enough about sokoban!
Could I do button puzzle?
YEAH
Could I do the rest?
HELL NO
It took me two days to complete the ending bit.

Now I can finally rest from this very challenging level. Ace fun, thanks, Roger.
More sokobans please...
EDIT: Sorry, I can't convert SUPASOKA. I just remembered that there are too many boxes. There is not a lot of butotns in Wonderland.
