Hi !
There isn't any death screen, because it is a part of the challenge. our cliché was "the journey is more important than the goal". So, by removing any death screen, our game is endless: you can't win, and you can't lose. Moreover, if you happen to hit a rock, you will come back after 5 sec or so, the music is reset and you can continue to play.
Yeah, it is not perfect about the boat, but it was close enough for us to be playable and enjoyable, although it is not like a regular boat.
