What canvas size and multiple screen size recommendations are there? Do I just build using HD 720 portrait? Do I have to build extra wide for non-mobile formats and center to view? Thanks!
Edit: It seems like I have to use Is on platform and build square canvas with keyboard for desktop/web and portrait canvas for mobile? Or am I thinking about this the wrong way and should I just use layouts? One for Desktop (square) and one for Mobile (portrait).
