Thanks for playing the game! Yeah the camera moves are jarring. I tried to ease this a bit by letting you continue in the direction you were previously moving, but then switching the orientation of the controls once you change direction, but its still a bit janky.
I think the audio issues are the browser. The audio is decent on machine, but pops a lot on my laptop. I found some Godot GitHub issues about it, but maybe there is something I could have done to make it better.
I'm glad you enjoyed the game!
