I really liked the split-screen layout, it was a really unique perspective for the gameplay! I also really liked the multi-tasking nature of the game and the touches of screen-shake also made the game feel very polished. The timing of the music starting when you set sail was very satisfying and added to the great sense of adventure the game creates!
The visuals were really good and worked well, I think possibly a more matching font for the text could have helped keep the aesthetic more consistent, but that is a very small detail in what is overall a very well made game! I had a lot of fun playing, I really like it!
