Man, what a comfy visual novel! I really like the slow pace of the story, and I especially like the sound mixing, cg, background, and sprites. They are all high quality. I also like how you provided so many options to customize the font style, size, and textbox, although it was hard for me to tell between the cream and white font colors.
I don't have many issues, since I understand this is still a work-in-progress. The prose itself has room for improvement, but you could always use a proofreader for that. I also found the default ambience sound was a little bit too high in volume for me, since I couldn't hear the voices and music in some occasions, so I turned it down. I also noticed the fading didn't work for some of the ambient sounds, but I think that is a bug of the renpy engine.
Also, a funny thing happened after I first started the game. When I first saw the menu, I noticed the continue button was clickable. When I clicked it, it crashed the game, giving me this error:
I probably wasn't supposed to click "continue" before first clicking "start," so that's just me being curious and stupid lol.
What initially drew me to this VN was through your backgrounds. I was especially amazed by how you edit the backgrounds from the real images; the first time I've seen them were when you posted them in the renpy discord, and every single edit you've made awed me. Correct me if I'm wrong, but I remember you posted a photoshop video tutorial for the backgrounds that one time. If that was you, can you please link it again?
Again, I think this VN has a lot of potential, and I can't wait to read more!
