Really liked the visuals on this! Especially liked the cast of characters with their portraits and descriptions.
Unfortunately, I did struggle a bit figuring out how to play. My first speed bump, my brain told me that "red X = bad" so I initially avoided it, but I eventually did try sailing into it.
After entering the whirlpool, I wasn't able to get past the wheel scene. I saw the Helm-Spinner mini game was supposed to match the coordinate, but it didn't seem possible to match exactly and straddling it didn't seem to do anything either. And I saw the Sailing Master mini game wanted me to press space bar in time with an indicator, but it didn't seem to do anything in this scene, and looking at the screenshots it seem like that mini game was intended for a different scene.
It feels like there's some really solid bones here, just needs some polish on the UX/UI and feedback.
