I figured out why I wasn’t getting sound from Firefox, it’s because I was missing the MIME type on my Nginx server. Got that straightened and found out that the game works great in Internet Explorer 9 also. So I went ahead and coded sound compatibility for all the major browsers. IE9 uses MP3 files for the audio and Chrome, Firefox, and Opera are all using the OGG files. Hopefully, I can get the game cleaned up even more over the holidays. But for now I think it’s great.
