Nice and original puzzle, unfortunately needed a bit of guessing with the clouds.

A BIT of guessing!!!! I can't get past the overhanging cliff!!! Any hints????

I agree with Cha cha - a hanji should be solveable by logic.

I'm stuck with little more than the cliff completed! Need clues!

There are some ambiguities in the clouds - and what´s more, the hanger doubles them... :(

The horizontal 11 starts in the first column, and the horizontal 13 in column 6.
They both form almost identical clouds (though the bottom cloud is partly of the picture, flat bottoms and three arches along the top.

Thanks for the hint Teesea :)

That was rather difficult, finally got it though.

Well, I don't know how I managed to solve that one. Thanks for the hints.

So much guessing, but possible.
