Not sure if this is a coincidence, but I couldn't help but notice nearly all of the spirit marks/writings seen through the lens are located around the bottom right of the screen. You know, "that" place.
I seriously freaking love these games and wish there were 100s more; so witty, clever, challenging and fun. You should consider taking these to the iphone / android, can you say rich beyond belief? I'd pay for it.
The painting on the wall in the "Time" room is The Garden of Earthly Delights, aka my favorite painting of all time. Thank you Art History and thank you robotJAM for being awesome enough to know about it.
