How do I flip canvas vertically?

So I want to use the infinite jumping game as a template however when I test it out with cocoon JS it's playing horizontally (on my phone). How do I flip it to play it vertically?

You have to set it up in Ludei to do that. Are you testing in the Launcher they provide if so you should have the new one and click the clogwheel and see and orientation option if you are compiling over the server before you send there is options to set it landscape.

you can always rotate the layout 90 degrees as an option
