In re that picture, one side of me says it does what would be the most intended thing well. Who would want to spend much time in such a bland space? I never have and never will.
Then there is the other side of the coin. If that is the first impression a person will take when looking in what motivates them to look further? The user interface is janky by modern standards and does nothing to explain or direct people past there. I have had a website supposedly with data I am curious about open for a few days, but just like that room nothing directs or invites me to look beyond that first page.
Maybe if you could mouseover, a pretty common option for most UI and get a hint of what would happen if you clicked Hot it might help. Right now it is a total crap shoot until you hit Hot and then you have a little explanation of the rooms that pop up.
