I have just created a series of 5 short tutorials demonstrating how to integrate a server side High Score Table into a Tumult Hype Project.
A couple of notes.
You will need to setup XAMPP locally to test this out, which is covered in the first video.
Once everything is working within a local environment, you will need to upload all of the files to a web server running Apache. Unfortunately, using dropbox.com as your hosting solution will not work, since dropbox does not run Apache.
Would love any feedback, as well as see any examples where users integrated this technique into any Tumult Hype projects.
