Thanks so much for playing! ^^ you know there's a high chance that the loud water sound is a known bug, it is unbearably loud when it happens so I think you might have encountered that, sorry :') Thanks for the feedback!
Anyone reading who has the same issue, It's fixable by a quick exit to main menu and then just continuing - though you might have to do it a few times, I'm not entirely sure why it happens or why that fixes it ^^
