First, after I export the html file I unzip it and open the index.html, but nothing happens after I click the "click to play" except that the words disappear. Am I exporting it the wrong way?

Second, I haven't yet found a way to write a usable sleep() function. I wrote like this as others say that it can work:

function sleep(n)

    local t0=time()

    while time()-t0<=n do end

end

But not only does it cause the program to lag, it also causes glitches. In the TIC() function, if I write draw something on the screen, then sleep(50), and then cls(), nothing will be displayed. I wonder how to realize a fully functional sleep()...

Thanks!

You have to use any local http server to load index.html or just try to upload your game to itch.io
