Very cool that everything was made from scratch!!! I especially like the music. I think if you work on the UI a bit (for example, add a top-bar for the health and contrast the colours) and do some polish work, that would really add to the value of the game. I would've liked to see a twist on the classic mythological story, so that the plot is not so typical damsel-in-distress / using women as a plot point - it would've been really cool if that was spun around somehow in a creative and trope-bending way. Otherwise nice, and very cool to see this take on the theme as I am playing many (too many) underwater games :D
