I was using 000webhost.com to host my game website. how do i do that?
do i need to make a html file that has game embedded in it or just submit the exported folder?
Develop games in your browser. Powerful, performant & highly capable.
I doubt they will let that last for long. Either way, just select HTML5 on export and you should be given everything in a folder. Just upload that to your server (000webbost) and call the index.html.
I create sub directories under my main site directory and then use Filezilla (FTP) to upload my exported game files to the directory. So for example if your site is as your link to the game and it should work. You also have to make sure your web host has the correct mime types setup for audio. Read the manual section on audio to find out what settings you need.
