Thanks for playing. It's just meant to be a scenery game half-derived from nights I've spent in the woods near me. No greater purpose or final ending, sorry.
And about the audio. I simply did as you tried: zipped up the audio with the html file and it all worked. I have encountered some audio lag problems with twine in other cases, so perhaps the audio was simply delayed it starting? Sorry I can't be of more help.
I'll give your game a go after i've made dinner.
