So, who has bought the game and would like to chat about it?
I’ll get things started by observing that Pixeltrickery attempts to one-up Failbetter’s Mr. Eaten content. That warning is no joke, though the game’s medium does allow for players to circumvent it with some clever programming. The result is kind of an honor system, with players choosing or refusing to accept the ultimate result. So I think Mr. Eaten retains his title, given that there’s no way of getting around his deletions.
But seriously, wow, I’d never seen anything like that before, however voluntary.
The Nier games did the whole "delete all save files as you remove the protagonist’s existence for the ending" before the new SMEN come out, too. Even made you input your name letter-by-letter and slowly blanking out all your statistics and collections.
As far as I know the game allowed you to play again, didn’t it? (even if it doesn’t allow you to play again it’s not the same as FL since FL can’t be finished other than if you do this and since the game still has content coming out you would only end the game here if you really didn’t want to play the game anymore, or if you are foolish).
