Hey there,
I added some amazing changes

1. A shortcut for ‘AutoPlay’ and ‘ResetScore’
2. Visual changes to font and button/text colors so that it has a better UI
3. A pop-up message displaying if user presses ‘Backspace’ to avoid mis-clicks

Things I learnt here:
Mainly I implemented addevenListener in js instead of using onclick in HTML, and I also had a huge logic for the pop-up thingy which is not as easy as it looks but it worked fine and I’m really proud :D
