Oath to the sea

Holy crap you used Dune in a game... Thats so freaking cool!!! I'm excited to see what else you make this is a great second project!!

Cute game full of charismatic characters.
You can't go inside houses, but you can stand on top of their doors, which doesn't look good.
There are places where it seems you can go but can't, and that can be confusing. Maybe make it so the character says they can't go there? (For example, the path to the top left near the sign in the village).
As Naomi, when you go up, there's a character hiding near the palm trees that you can't talk to.
There are some grammar issues, like using a double negative in "I don't think your parents wouldn't care" or something like that.
Great sound effects, but the music could use a little more work. However, it's still pretty fitting.
I also encountered the bug after meeting Ningyo, as someone pointed out. You can still pause the game, but nothing happens.

I couldn't progress the game any further, which is unfortunate since it was really good. I think you did a great job, and the story was very interesting. I didn't see any of the bad stuff you warned about, I can only be scared of what horrible events may happen.

Looks super cute!!
