first of all, i like the character interaction it has its cute, funny and sad moments, the story has a lot of potential but one thing that bothers me is the pacing of the story, its too fast in my opinion, like we get thrown a lot of key information from left and right simultaneously through out the game, i get that this is your first build and you want to tell the complexity of the story but we gets too much information on day 1 especially when this is a slice-of-life visual novel, in my opinion you can divide this first build to 3 days instead of just 1 to get a better pacing, like decide a key topic/information for each day and fill the rest of the day with the characters contemplating on that subject or fill it with a banter/skits or normal conversation between characters since its a slice of life vn.
other than that, the character sprites are nice, the music fits.
i'm looking forward to the next update and what kind of improvements that you make later on. :D (sorry for my grammar btw, english is not my main language)
