After today´s update the problem is gone, I could change the resolution and the screen is correctly redimentioned, I think this was some kind of bug with Double Fine games because I was having this problem with Costume Quest and Stacking too and now I can change resolution on these three games and everything works as it is supposed to.
Nothing extracted yet.
The game starts with my desktop resolution (1600x900), when I change resolution in the game, the redimentioned screen "cuts" some part of the bottom and right, it´s like if it was stretched over the limits of the monitor, so, some details in these areas are not visible and if there are buttons I can´t move the mouse over them to click. (I know this is a recurrent issue with some games, I just want to report it).
