Audio wise, that makes sense. It's my fault too on not adding a sound volume button as I only managed to add the audio like 2 days before submission ends. For web build, I will think of it in the future maybe. This is my first time technically releasing a properly built game, so when I have the time to learn it, I will try to learn how to release the game as a web build using Unity.
Anyways, thank you for the feedback!
