Nice puzzle game.
Good choice of music that changes based on the stage of the story.
Although AI generated, I still have to give some compliments on the art, the style is consistent and very much to my taste.
Loved the story, I played it till the end, I really want to know what happened to my redhead mermaid girlfriend.
One minor thing you can improve on: Some color of the tile is very light, and doesn't give much contrast to the white "path", and is really hard to see.
