[BUG] When the game is over, slicing actions still count toward the Score

[ChunhThanhDe]

🐛 Bug Description

When the game is over, slicing actions still count toward the score. This happens even though the game should no longer process any inputs after a "Game Over" state.

🔄 Steps to Reproduce

1. Play the game until the "Game Over" screen is triggered.
2. Attempt to slice objects after "Game Over."
3. Observe that points are still being added to the score despite the game being in a "Game Over" state.

🖥️ Expected Behavior

Slicing actions should not count toward the score once the game reaches the "Game Over" state. The game should freeze or ignore user inputs.

📱 Environment

• Device: Phone(web version)
