Move the game window by dragging the Title Bar when in Window Mode.
Dragging any of the game window's four corners will allow you to resize it.
To restore default settings, right-click the title bar and select "Restore Default Size and Position."

Setting the Fullscreen Mode Aspect Ratio (under Window settings, in the Config menu) to Fixed will ensure that the game displays accurately in full-screen mode even on screens with different aspect ratios.

Setting the Display Mode to Fullscreen, or resizing the game window, will by default employ a process called "Bicubic Scaling."
In most environments, this will work best, but if rendering becomes unstable or the game slows down, you can set Scaling (under Window settings, in the Config menu) to "Standard" instead. This will reduce the image quality, but may resolve any difficulties.

After changing Window settings in the Config menu, it is possible that the game does not launch or run properly. If this occurs, please check that the game is closed (via the Taskbar or Task Manager), then delete the "WindowSetting.sav" file under "SaveData" in the game's save directory. This will restore the game's default settings.

Then, please restart Windows and run the game again.

The game's save data directory is created when the game is first launched.
Under normal circumstances, the game's save directory will be created within the game directory.

Running other software in the background, such as an antivirus program, may cause problems with the game's installation or execution.
