I added a menu to enable/disable roles. My friend came up with a bunch of example roles for me to add to the game for testing purposes. We played a game of Mafia using these roles at school and it worked quite well!
I also made a bunch of small UX tweaks when running the website on a mobile device, specially for the host page. Most host page content boxes now render vertically when the screen is small to look better on mobile, and I fixed some overlapping or expanding pieces of content.
