Help with Theseus and Menotaur Chapter 2 level 2

I love this game. But, unfortunately you can't skip to next puzzle if you can't solve the current one. I'm stuck at chapter 2 level 2. Any help or way to choose other puzzle that I might have missed? I can't find contact info for developer to suggest one either gets hints or have option to skip a puzzle if feeling stuck. Thanks for your thoughts!
