    0% { top: 0; left: 0; }
    25% { top: 200px; left: 300px; }
    50% { top: 400px; left: 100px; }

    <button class="btn btn-light m-2" onclick="restart()">Restart</button>
    </div>
    </div>

    <script>
    let score = 0;
    function increaseScore() {
    score++;
    document.getElementById('score').innerText = score;
    }
