Problem: The leave game button and ready buttons are rather close to the channels list at the bottom and personally I find it annoying when I accidentally leave the room and have to rejoin. I'm pretty sure this isn't just me but if possible, at least move the back button to the top right and keep the play button where it is and have extra room for user's list.
Suggestion: conspicuous back/exit button at top left, extend the user/player list to take up the space that exit button used to occupy (Not all the way though), and that's about it.
