Higher Lower Game on Wix (Partial code is available on Github)

I have a Wix project that involves creating a Higher Lower game. The code for that is available partially on Github public. Here is the link: https://zeeyeah.github.io/HigherLower/

In addition to the existing features in the above link, I also want High Score feature.

As for designs you can copy the one from the above website or use any other design you want.
