You can test it out here btw! The LAA(...) is the search param. It encodes byte positions, so don't change the size of it, but there should be about 8 questions if you can manually encode byte positions to base64 ;)

The website I've been working on to load the settings finally accepts a search parameter, and displays the relevant game settings. In the example I've posted, the values that were encoded: 2, 4, & 5- correspond to IDs in a JSON file, and the three loaded settings are the result of the search.
