Changing the resolution is just completely broken.

-If I put it in Full Screen I have to uninstall and reinstall to go back to Windowed mode

-In Windowed mode the resolution I picked seems to have no bearing on Window size, each time I press update it seems to almost randomly pick a size of window to display

We will look into this as soon as possible. For now, feel free to edit PPC.sav in the Resources/Saves folder to manually change resolution settings. You may also use F5 to swap in and out of full screen at run time.
