The two greatest things of this game, in my opinion, is the art and the voice acting. The writing was good, too, but I have only one bad criticism and it's important: all the stuff of Shay having a strict diet, wanting to avoid sugar, his (at least initially) obsession with doing exercise... is not "healthy" but Eating Disorder inducing. I have experience with that and it was triggering. 

The part of spying on Shay and passing it as a good thing and "out of love" in the end, I think it's bad too, because it was out of fear, insecurity and maybe a little bit of jealousy, but not love. Regardless, the one major thing for me was the above.

With this aside, all the characters were lovable and I enjoyed especially the interactions between Chrys and Granny, they were the best <3
