Making the rooms all fullscreen and higher resolution so that there is more space to draw.

Basically when you join a room the screen becomes fullscreen only not the tiny one that there is now you get rid of that and make it fullscreen so theres more room to draw and make it higher resolution to compensate for the bigger screen. My idea is better then all other screen being to small ideas so use mine because it's the best idea for solving the screen size and resolution issue.
