Yep, since the site is new, for a while, until you get a good name, I also suggest you to use an escrow.
I like the fact that the block hash is used for selecting the winner. And also I find interesting the idea with the commercials, although I don't know what can be shown on such a small size. (Edit: I've seen now 2 bought squares, cool!)
What I don't like is that from every 2BTC you collect, you give out 1BTC as prize. I would have understood 20%, maybe 25% too... but half of the money is a bit much imho. And this is at 0.002BTC from the site, not the 0.005BTC from the ANN...
they advertise it as 0.002 for the first week only , each subsequent week the price of a square increases by 0.001 btc
till it reaches 0.005 , so I expect them to net around 2.5 bitcoins if they sell all of the squares
anywhere between 2 and 5 ,actually , but the HE of this game is ridiculous : 50%+ house edge its a rip off even for a lottery
10% affiliate comission is enough for people to promote the game , but I doubt you will be able to sell more than 10-20 squares for such a big price
after all its 80$ per square we are talking about and there is no explanation of how do we get the money back if you don't manage to sell the squares etc.
my opinion , the games like this one require huge marketing and a better concept to become popular otherwise they are stillborn
