EXPFall yeah the export went fine. I used cocoonjs because of the handy launcher app on my phone. So if it performed well in that, then it was going to be fine when I finally exported it.
There's a nice tutorial on here - cocoonjs tutorial. Not sure how useful it is now.. did scirra even enable cocoonjs support again? I haven't looked. As for cordova or something, I'd look into the tutorials. It always looks a lengthy complicated process, but once you do it once, it's just routine to do it again.
Hope it all works out for you
