I was just thinking HTML5 would be nice for the Jam, as that lets people play the game easily. I can keep using the 3.1 alpha though -  I was only looking at this bleeding edge build because the extra testing would help Godot.

Hi,

This is likely a problem with the Godot master branch, and not your build - but HTML5 builds doesn't seem to work. I'm getting this in the browser console: "Uncaught RuntimeError: memory access out of bounds".
