I've played the game for about 1 hour. Mostly just using Maya's flight to explore the map. Beyond the initial jungle along the river, there isn't much else (to see). There are a couple islands to the far north and north east. But mostly sand, sand, and more sand. I also couldn't find the location of the Christmas release (or they simply removed the torches). There is one region to the north that looks like a dried up river bed... and a large chasm... but not too much in the "interactive" gallery at the moment.
I'd prefer it stayed an interactive gallery, personally. I've played too many porn games with horrific gameplay elements and things that forces the player to jump through incredible hoops to get to the good stuff. Take AdeptusSteve's previous title, the Sexbot one... that one really forces you to jump through hoops to get anything interesting. If they do make gameplay and story and huge deal, I'd like the option to play in sandbox mode.
