This is a very interesting puzzle game, I love the creative use of the theme attachment.
Unfortunately I was not smart enough to beat level 9 and trying for over 1 hour I gave up... but I am sure it's possible.
Really Good Job!
Thank you for your feedback ! Yes , it is more than possible to pass level 9 , but difficult) levels 10-12 are easy , but level 13 is difficult again! This is done so that after a difficult level there are a couple of easy levels)
