idk if he can?
(btw i have been searching "zip to html5 converter" but it seems its not really possible to convert a zip game to a website game...but ill keep researching to see if I can help!)
well maybe I'm dumb but i will try to help you see maybe it's possible to make the website think the game was made directly there but without hacking to prevent stuff like lag happening so tricking it with a tool without messing up the code (i'm not sure you can even use code to make a website) so it might but might not work
