1. Simplified the content (related to the Bonus Image) in the upper right corner of the tutorial's initial screen.
2. Added toggle key information to the tutorial and battle screens (middle left of the screen), and the home screen (bottom center).
(The toggle key information in the tutorial and first screens remains, but in the battle screen, it disappears after the start of the game, just before enemies appear.)
3. Fixed some incorrect background image placement.
