Mouse cursor during story playback

• When the cursor is released from the icon, the selection is canceled to reduce erroneous operation.
  
• The mouse cursor is now hidden when operating the controller on the story screen.
  

Option setting tab switching with LR button

• Changed so that tab selection can be switched with the controller's LR button on the option setting screen.
  

Fixed typos in scenarios

• Fixed that Helen's dialogue was written as a researcher in Scenario 1-8.
  

If the mouse cursor is not used during story playback, it will no longer appear, improving the sense of immersion and improving operability on the option screen.
