The version has been updated. The changes are as follows:
■ Version 1.5.0
Added a "Chroma Key Background" setting in the configuration. When this is turned ON, the background of the puzzle area will be set to #000000. By using this as a chroma key, it is now easier to create videos or live streams with any image as the background. This can be configured from the "Settings" menu.
Fixed an issue where the BGM wouldn't switch when pressing "END" from the results screen to return to the title screen.
