hay, btw on mobile and Firefox, every screen gives a pop up say an “error has occurred on [websites full url]. You may be able to continue but sone parts might not work. Error:script error.”
We've tried the Itch.io version of the game on Firefox (on desktop) and mobile (using IOS), and haven't run into any errors. Luciana did encounter something similar on Google once. Can you try opening the browser under a different profile (even 'guest' would be fine), or as a private/incognito window, and see if the same error happens? Same device/browser, mind you, just a different profile of that same browser.
