"Gamey"? What would you like to see? That's what I'm wondering. What would make this more "gamey"?
People still love graphic adventures, for instance, and those are just as limited (if not more so) than this. Although you have to figure out where items go you are ultimately just clicking on things and listening to dialog.
The Walking Dead received plenty of praise last year and basically used this formula. What about Dreamfall? Same kind of thing.
I don't see the problem here. It's a modern take on the graphic adventure type of experience. These story based adventure experiences aren't designed to be "gamey" like a character action game.
At least this game has the chance to do something interesting with puzzle solving thanks to the ghost feature. You actually get a free camera, it appears, and the ability to look and move around while interacting with a number of objects. Figuring out how to help your character get through the environments by using the ghost is an interesting idea. Throw in possession and you have an even more interesting idea. For a graphic adventure, it seems rather robust.
