Be sure to disable your popup blocker on that site because it pops one up that asks for your age. If you have a pop up blocker installed then you can't get into the site.

Hopefully the game will have lower system requirements than what the web site needs to run.

I don't have any of the newer screenshots to attach because id doesn't want me to. grr
