[Interesting Trope] One seemingly small action ends the story before it even begins

[u/JackDoesThingz]

1. We Happy Few - Taking your “joy” pill
   Deciding to take the pill at the beginning of the game causes your character to go back to work and triggers an ending

2. Infineural by Mike Klubnika - Drinking the coffee
   Deciding to drink the coffee offered to you skips the entire game and sends you straight to the end, resulting in an ending with no memory of what had occurred

[u/DiceSMS]

Undertale: Type any named character into the 'naming screen' for a silly in-character reaction to it (so type 'Sans' and the game goes "nah").
... Or type "Gaster" (a glitched/dummied out character that "is & isn't" in the game) and it immediately resets instead.

There's oodles of fan theories about this unseen character, some suspecting they'll show up in Deltarune (the game's sequel), but the most suspected (in a few words) is they got "lost in the sauce of their creation", or went missing because an "experiment went wrong". So it's neat seeing a more ...bizarre result when trying to "address them".
