This is supposed to be a VISUAL NOVEL. A novel should "SHOW not TELL". All that happens is you have a few backgrounds that change and text says they "she kills you".
No world building. No background. No story, not even a hint.
You saying "she kills you" without ever giving even an imagined reason for any of this is not a plot. Not a story.
This shouldn't be "version 1.0" since that indicates a complete playable game. This is barely a demo.
