It's roughly 90% done actually. I've got thirty to fifty more chibi sketches to draw, four ending illustrations to make, and a few more music tracks to compose until I can consider it finished. The drawings and music should be finished by the end of this month, and the heavy editing/testing/re-drawing/coding should be done sometime in the middle of October, but I've been consistently missing my own deadlines recently, and I have a habit of adding more images where I didn't even plan to have any, so I really have no clue when it'll be done and ready to go.
If you're curious about the length, the demo is 1/5th of the entire VN.
