Cool game idea. Can you increase the time span though? 2009 to 2012 is a bit short for a game like this. Maybe like 2000-2020 would be much better. (I honestly don't know how much years can you fit in max and if 2000-2020 is too much but I really would like to see more of it.) And more room types would also be good. Walking across just 4 different room types is a bit low. And lastly a being able to crawl and zoom would make it easier to explore the gallery.
