I am not sure how long it will take for the author of the prototype, FreeMelody 0, to release the prototype work, as I have not communicated with him.
However, based on the response below the promotional video and the upload cycle of the two promotional videos, it may be within two months, but the exact time cannot be determined

Thank you for replying so quickly, weir! Do you know when melody's work will be finished, possibly?

Sorry, I am unable to reply to Grud's message in my region.

Why can't you find the prototype of this work in the works of FreeMelody 0? Because FreeMelody 0 has not completed the editing of the work details and uploaded them to the workshop.

If you can come back and see this message, I will put the video links of the unreleased works of FreeMelody 0 under this message, hoping to solve your problem.

Thank you also for the generosity of FreeMelody 0.
