This journey was such an emotional roller coaster!
The way the introduction was presented was my favorite part. Showing the player what they can expect if they don't fulfill a remnant's wish serves as good motivation in the beginning to do whatever we can to help Yuna. It was a nice set up that made me feel a connection with the characters and their motivations almost instantly. The story overall had a domestic, slice of life feel to it, surrounded by mysteries in not only how we can help Yuna, but also how Yuna can help Makoto as well. I got ending A and found it quite satisfyingly heartfelt. Though I am curious about the others as well!
I really enjoy the lore surrounding remnants and ghosts and can definitely see the similarities (and differences) with that of my own project's setting. It was a lot of fun to compare and contrast them along the way.
The little ghostie sprite was so adorable! I like all the silly variations. The playfulness of it was a nice way to add a little lighthearted fun, despite the tragic situation. Needless to say Yuna was my favorite character. I like her sass and enjoyed her interactions with Makoto. I found them quite humorous and entertaining.
I like the simplicity of the GUI. It felt nice and clean. Making it easy to read and comprehend, which is exactly what I prefer personally for a visual novel.
In the way of constructive criticism, while I liked the music, the sound effects were a little loud and over abundant, so I do wish that the two were on different tracks, so that I could've turned the sound effects volume down more while keeping the music loud enough for me to enjoy it.
Also when the sprites "jump", you can see where they are cut off, which made the characters looks more like floating busts than people. It looked a bit odd to me. As a sprite artist myself, I always make mine full body, to avoid this very situation. It would definitely be something I'd recommend if you plan on doing those kind of animations.
Other than those two minor details, I thought it was overall a nice story with a lot of heart, care, and thought put into it. Very nicely done!
