The Mead house demo on the top of the page returns the following error after loading: “Can’t find application source. Please re-upload your application.”
The Lake apartment demo below does start however. It takes about a minute to load. Movement is smooth but it has about half a second to a second of input lag.
In “Free mouse mode” where the cursor is visible, you are unable to turn around 180 degrees without leaving the viewport with the cursor and coming back in from the other side. “Locked mouse mode” works better in that regard, however it prompts you to press “escape” to leave the locked mouse mode, but instead it closes the stream since the same key is bound to close the application. The viewport turns black and the cursor remains missing after pressing escape. I had to force quit the browser in order to use the cursor again.
