In terms of pure gameplay, it's very well made. Very, very well made!
I wish the art was more consistent, and I wish there was more feedback on when you click something and it doesn't work, or it does work (it took me a bit to figure out you could only upgrade things in the shop menu, and how to do so). There's a few things like that, like when clicking on something like a weirdo and not knowing if it's doing something or not.
I wish the art was more consistent too, but I love that you have a character and a weirdo. It breaks up the gameplay nicely. I don't really like these types of games sometimes, but I can see the vision here!
In future, I would focus on making some things clearer to the player, and keep having fun little things going on! Also, when the character (Scarlet?) said "the ocean holds many secrets", I clicked around there for a while, but found nothing. Did I miss something?
Not bad, keep it up!
