For those who are interested in uploading to itch.io, it’s pretty straightforward.
Download the web version from Playcanvas (You’ll have to be a member)
Upload that same file to itch.io publish game section (be sure to click the option that makes it an HTML5 game)
Input the preferred dimensions and publish.
Pretty straightforward. I plan to put together a more in-depth solution to get a ‘setup’ file or ‘exe’ using electron for those of you interested in putting your games on other platforms like steam or distributing it yourself.
