Thank you for your suggestions and for taking the time to leave your comment! I really appreciate your positive feedback on the animation and the VN's story.
I will take your suggestion about the sounds into account to enhance the gaming experience. Regarding the sandbox, I understand your point. In DBF, the focus is on providing a classic visual novel experience with sandbox elements, allowing for more focus on individual stories. Although it may seem a bit boring at first, with future updates you'll see how multiple stories unfold, almost like playing several VNs simultaneously.
I invite you to check out Irreverent Heresy if you're interested in a VN without sandbox elements.
As for reviews or ratings, I've grown accustomed to it. Whether with a sandbox or without, the feedback tends to be negative. There are even devs who automatically downvote my releases, leaving negative reviews to demoralize me and reduce visibility for my projects.
