I got painfully stuck because I'm an idiot. I didn't understand you could walk, so I got down the stairs and couldn't do anything else. Then I found out I could walk, but I had spent so much time on the second row that I forgot I could walk also on the top left picture and got stuck again because I had no idea how to reach the top right.
Once my brain cells started working again, everything went fine. I'm so glad I tried again because it was a lovely game.
Except when I found stoc***o in the grass :P
