In case you don't know, you can use turbowarp to package games into HTML files. A lot of people don't know about that, so i'm try to make sure it's well known.

Oh yeah I use that all the time! Thanks for telling me though - There's also another website that only lets you convert to HTML or ZIP, but here it is: sheeptester.github.io/htmlifier My game was converted using TurboWarp Packager though.
