Congratulations on finishing the game!
Despite the simplicity, you managed to create a sense of anxiety and increasing tension as the game gradually speeds up, whirlpools and mermaids everywhere - it's almost like being in a real storm, you have no hope, but you're just rushing forward.
Nice pixel art. I also like the way you animated the water - it looks like pencil shading, creating the feeling of stop motion animation.
This game does not hook you for long, but it gives you fun in the first few starts and the feeling of surviving a shipwreck.
Good job!
