Looks like a good project to learn from. It did take a while for it to load. Lots of functionality covered. I didn't find the donut which was a little disappointing. 

I found the camera controls didn't work well for me on the browser, perhaps there is a way to capture the mouse pointer. I had to keep moving the mouse off screen and then back on to turn around. Or perhaps consider using Left and right arrow to turn rather than strafe.

I think we used the same Town pack! Did you design your town? I'm just wondering if there was a demo scene that I didn't look at.
