const hitNotesSet = new WeakSet(); const tolerance = 10; // hassasiyet

const arrowMap = { '←': document.querySelector('.arrows-container .arrow-key:nth-child(1)'), '↓': document.querySelector('.arrows-container .arrow-key:nth-child(2)'), '↑': document.querySelector('.arrows-container .arrow-key:nth-child(3)'), '→': document.querySelector('.arrows-container .arrow-key:nth-child(4)') };

const keyMap = { '↑': 'ArrowUp', '↓': 'ArrowDown', '←': 'ArrowLeft', '→': 'ArrowRight' };

function hitNotes() { document.querySelectorAll('.note').forEach(note => { if (hitNotesSet.has(note)) return;

    const arrow = note.innerText.trim();
    const target = arrowMap[arrow];
    if (!target) return;

    const noteRect = note.getBoundingClientRect();
    const targetRect = target.getBoundingClientRect();

    const noteY = noteRect.top + noteRect.height / 2;
    const targetY = targetRect.top + targetRect.height / 2;

    if (Math.abs(noteY - targetY) <= tolerance) {
      const key = keyMap[arrow];
      if (key) {
        console.log(`Basıldı: ${arrow} (${key})`);
        document.dispatchEvent(new KeyboardEvent('keydown', { key }));
        document.dispatchEvent(new KeyboardEvent('keyup', { key }));
        hitNotesSet.add(note);
      }
    }
  });

setInterval(hitNotes, 10);

I have a better solution:

F12 -> Storage -> Local Storage -> https://neal.fun

Select "not-a-robot-level" and change this value from "46" to "47"
