One Page Wix Website (similar to already existing Github page)

I need to create a higher-lower game- https://zeeyeah.github.io/HigherLower/ like this on Wix for me. This same page is available on Github (public), so the code is already there, you just have to copy paste it and rework it for the Wix, such that I can upload the data in CMS and that would get reflected in the game.

Addition to the existing game, I want just one more feature- The high score should be stored and shown on the left bottom below the current score.
