"Every game, there's something behind the waterfall. Or there should be. And this game does not have that, so far. You have to hide a secret behind the waterfall. I don't care what game you are; even if you're a space game, have a waterfall, hide something behind it. As a gamer, my instincts tell me to do that, and I'm satisfied when I'm right."

— Vinny, playing Delver

(The two main characters are bracing themselves to run and leap through the waterfall.)
Solar: Imagine if there's nothing behind the waterfall and they just died here.
Dovey: That would be bad.
Aura: I should make a hack where that happens and then the story is just based on two completely-different characters for the entire duration.
Solar: (Laughs) Shows this scene for the first scene and then it's 'Oh well! New guild members.'
Aura: No, like, you start the hack and think that it's just like unedited Explorers, you think that the hack wasn't patched, but then you get to this scene and they just fucking die here and the hack just follows two other Pokemon.
