I got the above mentioned controller now, and it seems rather sturdy and nice. However with the iphone 6 attached on it, it's rather heavy, so I might instead play on an iPad with the controller free.
Too bad Ashley didn't reply to this thread. Also, I have since switched over to coding in Unity, since I was not 100% satisifed with the HTML5 performance. Well, I still like C2 and still have a license, maybe will make other kinds of games on it in the future.
Enjoy all, and if anyone has a game in C2 they want me to test with this controller, just PM me. See ya!
