A very solid retelling of Swan Lake! I'm rather a sucker for re-tellings of the classics as VNs. All said, though, I see you have voice acting and music listed, but for me the game was entirely silent. I played the downloaded build in English, and I'm not sure if that affects things, but I think if nothing else, the music would elevate things for me, personally.
All said, congratulations on all of your hard work, and congratulations on the release!
