Fixes an issue where the menu screen continuously refreshed (blurry effect) whenever any key was pressed except 'p'.

Details

• When pressing any key other than ‘p’ on the menu screen, the program entered an infinite loop because the key value was never updated correctly inside the input loop.
• This caused the screen to flicker continuously (redrawing every cycle) and prevented any further key presses from being detected, including ‘p’.
• As a result, the game could never start once a non-‘p’ key was pressed in the menu.

Fix

• Properly initialize key and update it inside the loop using Keyboard.keyPressed(), ensuring the loop exits when a real key is pressed.

Result

• The menu no longer flickers when pressing non-‘p’ keys, input is handled correctly, and the game starts normally when pressing ‘p’.
