The promised fix to the fullscreen issue has been implemented into the beta of version 2.3. You can toggle between fullscreen and windowed mode now using F5 ANYTIME in-game. You can also switch the aspect ratio using F6. There have also been some other changes to prepare the game for porting to other platforms. One you may notice is the change to the System Options. While the change seems minor, it affected how we check if "Voice Acting" is toggled. In updating this, all previous Autosave files will no longer work. You'll receive the following error if trying to play an old game file: https://dl.dropboxusercontent.com/u/6954576/Screenshot%202015-06-16%2011.45.28.png That's why the game will remain in beta for the time being. After the Steam Summer Sale is over and activity has died down, I'll be moving it to the public branch. If you want to play the new patch with the fullscreen fix before then, you'll have to opt into the beta. You can do this by right clicking the game in your Steam Library, selecting Properties and going to the Beta tab. From there, you can select the BETA from the dropdown. Enjoy!
