Spoilers below, so go to https://www.deltarune.com and download the "survey" if you haven't already!
So, chapter 1 of Deltarune is out! Is it just one chapter of a game that will be released in chapters? Is it simply a demo of the full game? I don't know, but there's a lot to discuss about it, so I started this thread so as not to clog Activity like I almost started to do!
I'll start with some general observations and speculations I had.
Obviously, Kris is Chara, and I'm pretty sure the game is set before Undertale, but the relationship of the town to the sprawling locations in Undertale is unclear. Also, the monsters are living on the surface, but Kris is the only human around. Are humans and monsters still living in peace? The fact that "humans under your bed" is something to be afraid of implies no, but if that's the case, why are they still living peacefully on the surface? Maybe they're just racist against humans. Or maybe the monsters AREN'T actually living on the surface, but underground, but the Underground has not become dark yet, and this is the tale of how it became that way!
