No audio unfortunately, and I did have to play it in single player mode. The maze is quite difficult, and the bonus of more vision from the houses helps quite a lot. I'm not sure if I had to fall through a trapdoor to find the exit, or that it just teleported me to another spot? The game looks quite nice either way.
Oh I should mention you have to extract the zip somewhere for the server to work, I've been playing these games directly from the zip so I found a little snag there ;p
