- Added a pop-up that explains the skip function when loading a saved game for the first time.

> Dev Note: I wanted to make sure players who are new to visual novels understand how the skip function works, so I added a short explanatory pop-up.

- Adjusted the sound effects to play with echo at 69% sanity or lower.

> Dev Note: I felt that combining echoing sound effects with the already distorted music below 70% sanity would enhance the unsettling atmosphere. That's why nearly all sound effects - yes, even button clicks - now have an echo when sanity percentage is under 70.

- The requirements to unlock the 12th secret achievement have been reduced by 50%.

> Dev Note: Since it's a secret achievement, I won't reveal the exact numbers. That said, the previous requirements felt a little too demanding, so I decided to make them more accessible.

- Increased blood color saturation by 30%.

> Dev Note: Blood stains are important for conveying the game's darker side. At 0% sanity, the stains looked too black, so I increased the saturation a bit to make them clearer.

- Screen color saturation during the 'Low Atmosphere' mode increased to 60% (was 50%).

- Screen brightness during the 'Low Atmosphere' mode increased to -15% (was -25%).

> Dev Note: The previous low brightness and muted colors conveyed the tension in school well, but made the game look a bit too dark. So I increased them slightly for better balance.

​- Reduced dark vignette opacity in the second main menu variation to 35% (was 50%).

> Dev Note: The dark vignette effect made the menu appear a bit too dark, so I lightened it for a clearer view.
