Haha, I have no clue why only the music audio is so loud, I looked it up and apparently its a webgl/encoding issue and someone said to reimport with audacity and I did that but it didnt solve the issue :P Glad I added a settings menu though!
Thats probaly why others that choosed the same game didint make a WebGL version. But the game is really good! Maybe a solution would be to change or remove the music?
