I have the HTML 5 plugin for GMS2, I TRIED to deploy my game that way, however, when I did the UI was all messed up? I will need to look into what went wrong more in the future, but due to the tight deadline of the Jam, I had to just deploy windows and call it a day.
Edit: I'm assuming there is a simple reason everything went wrong, and I'm just not familiar with how it deploys to HTML5, but I was bummed that it wasn't as easy as just swapping it over to HTML5 and calling it a day.
