I might add to this that yes, C2 has some problems on mobile (it is more mobile that have problems with HTML5 but whatever):
(Before everything, I do HTML5, I bought C2 for that and not for pseudo-native applications or something else..)
-the fact is that if you plain on doing Web HTML5 you'll still struggle with that anyway, and would have to do even more work, but yes, it can improve, I agree on that point (even though it shouldn't have to improve on old devices that haven't what it takes to even read HTML5 I think, but just my opinion).
On the other hand, you have mobile via wrapper, yes:
-CocoonJS is something I never liked, I just ignore it, not a thing I'll ever use in my life, I'd rather not making .apk nor iOS apps than using it.
-Crosswalks is chrome for android, and since I am doing HTML5, it is perfect for my needs, my tests (without audio I must say) were great, maybe it is because I always program in a safe way, so i can optimise easily, I bet that crosswalks is already better than CocoonJS for some games, and it'l improve even more, not worried.
As for the marketing of C2, I agree that it could be clearer, but if you plain on buying it, the free edition is already a good bet to learn to use it, you can export to HTML5 that you can test on a mobile browser so you have a first look, and for cocoonJS, I'm not sure if you can package C2 HTML5 exports with it to test (I mean license wise, pretty sure you can upload HTML5 files to cocoonJS for testing in theory), I think we need an awnser to that question, so peope can test it first.
