Yes, I'm sure it was because of the game and not because she was very sick.

I was gifted a copy of Undertale but I never installed it. I've never had any interest in the game. Didn't even know it or its fandom existed until semi-recently. Flipped through the wiki once, decided it was another example of an over-hyped game.

I actually have pretty discerning tastes, but when I say it that way it makes me sound like an insufferable pretentious jerkwad.
