Adding some sound effects and bug fixes

Still changing a bunch of things with the web build. As I add new features, like sound effects when you rescue people, and them saying thank you. I'm also introducing new bugs. But, fret not this is not the final update. I just wanted to add a few nifty things to the build. I have a few more plans for the game such as... an actual way to win 😅

I hope you've been having as much fun playing the game as I have been having making it.
