The writing is top-notch in quality and the characters are interesting even during the early moments. The Barkest Moment is a clever little section too, I love meeting Alon after doing something stupid and getting sassed for it. It's been an entertaining two days of playing it, and everyone is a good boy except for Teak.
Joking aside, my only complaint about Teak is his rampant bigotry. Even if I have a solid idea of why he's like that, it doesn't really make it fun to be around that character when all he ever says to the player character is how stupid and useless we are. I get that his antagonism is a driving force in the story, but all he's done is bum me out and make me avoid any scene that involves him. Unless he seriously changes, I would throw him out of Shelter entirely after this whole fiasco.
Other than Teak though, I've enjoyed every moment of this visual novel and recommend it to anyone looking for an overall wholesome story that grows into something very exciting and allows for quite a bit of character growth..
EDIT: So I wrote all of that before replaying through other scenes, I can now safely say that Teak may be a good boy too.
