Thanks for the feedback! An undo button would be a great idea (though I don't know how to do that but it's still a great idea). The last image rotating was more to try something else so it's not too repetitive (it's probably rotating a bit too fast, I didnd't balance things much). The goal of the game isn't to stay too long on one puzzle to hit perfection, but more to have fun building something as best as we can. A rotating image surely isn't the best gimmick we could have added to the game, it was more like the easiest one but with a bit more time we would be able to create some more inventive levels eventually!
