These are GREAT!  I love the smell as well, too bad it won't last.

Glad to see you can solve some by flipping pieces I was wondering if that was a "foul".

I was also wondering if there is an "answer sheet" somewhere?  I got one as a gift for a puzzle nut friend who will love trying to solve these.   Me I would like to give it a shot each morning, but then look it up and change it if I can't figure it out before my work day starts.  It's like those infinite calendars where you change the month and day blocks, but way more fun (for me).  

Lastly, out of curiosity, does July 5th mean something special that it is the date they are shipped with?

Thanks again, great Kickstarter project, definitely going to have to order more puzzles from the site.
