I believe I might've run into one of the bugs you mentioned, as I could not hear any music or SFX while playing the game. I don't blame you though, as most likely it was because I am using Opera, and lots of web browser stuff really doesn't like it for one reason or another. I love the art of the main character and the ship interior, but I swear I could not see any fish I was catching either.
Either way, this is a great submission! Hope you continue to work on the project!
