First of all, the game is really, really, really beautiful!
And the gameplay is very interesting. I have to admit that it took me a while to get used to the controls. But you get the hang of it!
And maybe it's just a detail, but the end screen blew me away! That exhausted face and gasping breath had an incredible effect on me!
As for the difficulty, I have to admit that I defeated the final boss (the one in the middle) in an inglorious way (I stood in front of him and threw and recalled all my scissors, frantically and without trying to avoid his attacks. In short, like a brute. Having all the scissors, this strategy worked :D)
Anyway, well done for a great game!
