Oh darn, let us help!
Have you tried moving the mouse and clicking the left mouse button while holding the 1(&|) key?
There is one small bug that causes the tutorial to bug out when people tab out of the game during the voiced tutorial, so don't do that.
We hope this helps!

Thx for the video!! Due to your video I can see that the audience lights buttons and spotlight don't work but the baked(non dynamic global light) does show shadows. So it looks like your browser + graphics hardware are having trouble with the realtime/dynamic lighting. Sadly that's the whole concept of the game haha. The only thing I can suggest is try a different browser as they use different webgl renderers. But thanks already for the effort!
