Woah, good 3d graphics, but the game really starts to shine when you see how many websites you need to go to, which contain clues.

They even incorporate in e-mail messages to get further in the game.

Can you find Jon?

Is there supposed to be sound?

I had mine turned down, but I don't think so.

Although the radio in the living room appeared to play some tracks.
