English isn’t my first language so I don’t really know What a cache is, could you explain What i should do?
No worries! To be honest I'm not an expert on the technical details myself, but I think it's a bit like how your search history is saved by whatever browser you're using (like Chrome, Safari, etc.)? I'd recommend downloading the .html file and opening it directly instead of opening through the itch.io page. Hope that helps!
