Here 's my latest Simon Says game.Any advice welcome

I am attaching my most recent Simon Says project. Would appreciate feedback on it. Here is the linkhttps://codepen.io/Ajax-2031/pen/EbQJBY

Hi. This looks very good. I won!
But I was expecting a congratulations message and sound.

Thanks for replying i have changed the game to show if player has won.Here is latest Link https://codepen.io/Ajax-2031/pen/EbQJBY

I’m sorry I was gone awhile. Great job.
I would only suggest that the winning announcement be a little bigger - exciting that you won! type energy.

Thank you for replying.I have changed the winning announcement to larger font size.Should be fine now thanks.

I found a bug. If the user correctly clicks out the correct sequence, but then accidentally clicks on another button before the next sequence is played, it messes up the game from there on out.
