Some feedback.
The intro is too long. Maybe warn people that they will be playing a rather linear vn for half an hour (or more, I paused at the city gates).
But it is very good, if I may say so.
Your game is too big. You do not even use max compression on your lossless png. With so much colors (>10k) in the pictures it means there is color continuum and that compresses good in lossy formats like jpg. This ain't pixel art, nor a print master. You could shrink most images down by 90% and no one would notice the difference. Try making a jpg with factor 75 and do a blind test for some pictures and see for yourself if you can tell the difference. At this rate you will hit file size problems and limitations soon, when you add new content.
Did I mention that I dislike kinetic vn stories and still endured your intro ;-) If you keep that level, people would play your game even without the boobs.
