Good job. The story is very good and polished.
In term of art, gameplay and environment are perfect match.
Some dialog [2-3 dialogs] are over the frame, but overall is good.
If you have bgm or mermaid [siren?] sound, it will be better.
thank you! I'm not sure what you mean by dialogue going over a frame, and I'm not sure what else a siren or mermaid would sound like (I've used some sounds already for the mermaids song itself/vocal) but thank you for playing!
