A visual novel for a game jam is a very brave decision. The genre is extremely hard to produce in a short time crunch without using stock/paid assets. I don't know how but you pulled it off! The visuals and dialogue are really good! My only gripes are with the quest system and the colors.
While it's most certainly due to the time crunch, I would've loved to see the quest system used more than two or three times, even at the cost of lower-quality dialogue, or reused set pieces.
As for the color, I really love the monochrome style. But I find it jarring that some of the frames used color. I suppose it's for the fire considering how it's stylized. But if I were to continue this project, I'd make sure to save color for elements requiring contrast, like fire or blood. Please remember to make blood red. Or you might have this happen to you.
Would love to see this worked on into a full release!
