hi! i was able to recreate the issue (assuming it was following an error message regarding "no valid storage adapters found") and it seems like the issue is that either your web browser version might be too old to support the local storage functionality required by SugarCube engine, OR you've got cookies disabled on your web browser.
i'd try enabling cookies (cookies may be automatically disabled if you're using google chrome's incognito mode) and test it out again, but if you're still having problems, please let me know, and i'll see what i can do! 💖
