Interesting concept. I got a bit confused at first with having to open a second screen which wasn't a separate "state" and the fact that what you add is supposed to be invisible (it's writtent AND it's the cover art, but it happens :D ). I think it would have been cool to be more cohesive, like having the 2 screens present right away. AND not having a restart of the editor when you fall.
But the twist is really cool, simple but very effective, good job !
