If you directly edit this game's .html file (or indeed the .html file of any game made in the Harlowe variant of Twine) you can enable console commands to edit any variable directly, similar to the default behaviour of the Sugarcube version of Twine. Simply add the following code to the Javascript section of the page:
JavaScript:
if (!window.harlowe){
window.harlowe = {"State": State};
}
For this game in particular (on the current version at least), inserting this code on line 25 (just under
/* twine-user-script #2: "external scripts that rely on jquery" */
) is a valid location for this.
Then, open the newly edited .html file, and the full list of variables can be accessed and modified from your browser's console (F12) via the following command:
