EDIT: The below information is outdated as it appears we've fixed this problem. So fullscreen should work for Fatal Theory now.

We encountered an issue with our Mac OSX builds where toggling to fullscreen would outright crash the game. We've removed fullscreen from the display menu, but added extra windowed screen sizes so you can still enjoy it at a larger resolution.
We can easily add new screen sizes to the list too. If it's still too small for whatever massive display you may have, let us know your screen size and we can work with it.
But we just can't do actual full screen. From our tests it seems to be a problem with the framework we built the game in, SDL 1.2 (although we'd love to be proven wrong on this, because it'd mean we could fix it). If that's the case, our only option would be to migrate the game to SDL 2, which at this point would be a massive rewrite all for the sake of fullscreen compatibility on Mac. We just don't have the time or resources to do something like that. So different window resolutions is all we have to play with right now.
It's disappointing I know! We wish it worked too. But windowed isn't so bad, and the gameplay is worth it. If you're teetering on the edge and wondering if you should still buy given the issue, remember you have 2 hours in which you can get a full refund on the game -- use it! Try it first. And let us know your thoughts either way :)
