The clicking sounds stand out to me, but I don't remember.
Didn't notice there was another ending until I read the itch description.
The key ending should be a bit more diegetic.
Maybe some dude, some demon comes up to you, and asks you this, though it'd still be pretty weird for it to be an input, or some multiple choice option.
It's narratively fine other than it's place in the story, but should be done way differently, how is up to you.
