A bit unclear-- just an idea to improve

Just a suggestion to improve the game:

Edit: i have just realized you have used console.log() to log 'game is save' but not all people apart from developers check the console

When you click the 'save' button it should tell you 'game saved' in a dialogue box by using:

<button` onclick="myFunction()">SAVE</button>
<script>
function myFunction() {
    alert("Game has been saved");
}
</script>

or display a tick or beside the 'save' button
or..... grey out the 'save button' and replace it with 'saved'
