It's funny how the kill screen totally makes the game.
If there were no kill screen, there would be no reason to point press or to develop the skills to do it. You'd just run boards until you got unlucky 4 times. The kill screen forces you to learn everything about the game and max out your ability.
Where it happens also works out really well. At L22, it's deep enough in there that it takes hours and a lot of skill to get to, and you need a certain amount of luck. Yet there aren't so many boards that you need rare, silly luck.
It also just happens to be in a spot where it's possible to roll the score (plus a little further), yet you have to put in a special effort to do so.
The kill screen is the masterstroke of the game's creation, yet it's a total accident. They really couldn't have designed a better "feature" (or picked a better spot in the game to hide it) if they tried!
