Turnover has been updated to v1.0.865.
This update adds a Borderless option in the Fullscreen setting in the Options screen.
Borderless full screen is a windowed mode where the window is resized to cover the entire desktop and all "window dressing' is removed. It plays nicer with alt-tabbing, multi-monitor setups, or other situations where the normal full screen mode may have issues.
To try it out, go to the Options Screen, and change the Fullscreen setting to Borderless. Your desktop resolution will automatically be selected.
Note: Borderless full screen mode is only available for your desktop resolution.
