How to Play

• Drag English words to their Dutch translations.
• Correct match: +10 points + streak bonus.
• Wrong match: -5 points, streak resets.
• Double-tap/click for a hint (flashes orange + speaks).
• Hints reset streak and award no points.
• Mute button toggles all audio.
• Master all {RAW_DATA.length} words to win!
