The knife will get you a pelican and the nail will get you a carrot and a tongue... Even after getting 9 endings I still can't predict what an icon means. And that's AWESOME!
Although it's not a game I'd want to play more than once, it got me completely hypnotized from the very beggining. It's a masterpiece, the music and the drawings are exquisite and the subtle storytelling catches the eye, but not interrupts the gameplay. 5/5
