Thanks! I'm really glad you like it! It is hard to find your partner by design. ;)
I have not heard of that bug with the ambiance... It's a long track so I might have forgotten to set it to repeat. As far as pausing when you click out of it, I don't have much control over that, unfortunately. I think Unity's WebGL player just pauses when it's not active. If you have a mouse with a scroll wheel, you don't have to click out, but with other input methods, maybe you do.
That said, I may at some point make a downloadable version that has some camera panning action to make it a little more approachable for folks. :)
