Thanks for the comment! There is supposed to be music, though... are you hearing the jump sound but no music, or is the audio entirely broken for you?
I am hearing Jumping Sounds, but no music
Strange. Sorry about that.
Also not getting music, maybe just in the browser version?
I think maybe it's the relative volume of the music vs SFX? I adjusted the volume of the music down because I thought it was too loud originally, but now I find that when I turn my computer volume down I can hear the SFX but not the music.
