Yep, I have the wrong meta tag I believe:

        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />

That should fix it, I'll push a new version after fixing the word matching issue others have pointed out. I underestimated Wordle's complexity :)

i see it slowing down on mobile safari as well

will be a great chance to optimize the hyperscript runtime for mobile
