There are a couple of typos in the script, which isn't really a problem but I appreciate when people notify me about stuff like this :D
I'm an English Studies graduate, so I'm very familiar with the concept of literary analysis. In that regard, this game kind of felt like being back in class HAHA. Kai and June are really cute characters, I wish we'd gotten to see more of them as people! Is Kai wearing hearing aids? That would be such an interesting thing to explore in a possible sequel hehe... Mary is an adorable character, too. I want to get to know her better too!
The illustrations were really cute and I particularly like that they're positioned at the end of the routes. It makes you feel like you've truly gotten close to the characters over time, as opposed to them instantly liking you. Keep it up!
