What the hell is a kill screen?
At a certain point, the game just kills you and then ends.
Is it a set point? Like, should he have known about it? If it's random, then this shit is about as valid as being the world champion in Crash Team Racing.
From wiki
Donkey Kong also featured a kill screen in the 22nd stage, and the 117th screen. This is an example of a kill screen that is not due to an integer overflow in a level counter (since programmers prevented this),[2] but a different oversight on the part of the designers. The amount of time allowed for any given screen is determined algorithmically during play by the level the player is on. The timer is calculated 100*(10* (level + 4)), and has a maximum value of 8000. When the level reaches 22, the game reads 100*(10*(22+4)) or 100*260. However, the 8-bit counter rolls over at 256, meaning the game calculates 100*4. This causes the timer to be set so low that there is simply not enough time for the screen to possibly be completed. Steve Wiebe got this screen when he attempted to beat Billy Mitchell's high score record on Donkey Kong.[citation needed]
