Mainly in part of the sense that it is almost like a continuation of this VN here (https://echoproject.itch.io/khemia) in some shape or form one way or another (at least from how I see it from my perspective) as it focuses on how both Amicus and Marco spend their remaining time together before the human has to leave for Earth again.
Additionally, do you have any plans to redo, edit, change, or revise the story for that visual novel, whether at the beginning or based on what you currently already have available on that visual novel there (https://echoproject.itch.io/interea) specifically?
Not only that, but perhaps your most popular and well-known visual novel (also known as https://echoproject.itch.io/adastra) could also benefit from those improvements as well (?). That may involve you doing an "artwork rework" again or a complete redo, edit, change, or revision of the story. Enhancing it with more choices, options, alternative storylines, and different endings could greatly enrich the entire experience of the VN than ever before—only if you are interested in pursuing that type of ambition for it at all (?).
