Thank you for playing!
Bitsy games do not support sound (to my knowledge), so you aren't missing anything there! As for the loop, I see it was unclear; bitsy games automatically restart upon reaching the end. Once you reach the final room nothing new will change about the experience. While you might consider the looping nature a part of the story, you needn't worry about missing anything there either.
If I ever update or expand this little game I'll let you know. I'm glad you enjoyed it for what it is!

It's useful feedback that someone unfamiliar wasn't given enough information to understand! I might update the page later to give some more scaffolding.
If you're interested in playing more little games in this engine (or making some yourself!) I highly recommend starting here: https://ledoux.itch.io/
Ledoux made the engine and has some games that are far more complicated than this one you can try out. He also keeps a collection of other people's games on his page!
