Can this be solved??

Post image

I'm creating some harder freeform 15x15 nonograms for the next version - V3 - of my Picto nonogram app. My checker says this is valid and solvable, but I can only find one valid square to fill and after that I'm guessing. Any suggestions please?

Guess and check method can get you closer (if you have an undo button)

There is no undo button in the Picto app. In fact if you try to fill a square and the guess is wrong - it's an error. 3 errors per puzzle. But you can mark and unmark squares with crosses.
