same problem here... i made it through the tutorial... then when i get to the main menu with waterfall in the background... i get a pop up saying something about choosing a name and has a button named "ok" on it but it dissapears before i can click on it... the game doesnt freeze but you cant do anything besides click on a few items like the number of coins you have to see a little dialog... can someone please share how you got this to work?
