I'm having an issue loading the game on a retina macbook pro running 10.9.3. The issue is similar, though not quite the same as the issue reported here:

After playing in full screen, relaunching the game results in an interface that is "zoomed" to the lower left portion of the screen. What I mean is that all elements, including the mouse cursor, are huge; maybe 8x or more larger than they should be. This of course, results in all clickable elements of the interface being off the screen, since only a tiny portion of the game actually fits on screen. Clicking anywhere has no effect (unlike in the bug noted in the link above). The only thing I can do is command-Q to quit. As recommended in the link above, I tried deleting ~/Library/Preferences/unity.QCF Design.DesktopDungeons.plist -- this had zero effect, the game launches as before. I also tried changing the resolution of my display before launching the game, with no effect. Could not change it after launching, as Command-tab and other shortcuts are conveniently disabled while the game is running.
