Hi :)

Well made visual novel.

Mannequin characters are always great, I like them :)

Sea pictures are great and the music goes well with the story 🧜🖤

Is there a third path ❓


No, there's only two paths and they both end similarly.  I was going through a rough time when I wrote it.  Also I ran out of jam time.


I understand, life is not often easy that for sure.

After the 2 paths I was not sure there were another path so I asked just in case :)
