There are a few game pads out already, I personally have and love the stratus. It works great with the games that do have controller support, steelseries put out an email for developers as well to help. Again really excited for your game it hope all goes well. http://steelseries.com/stratus-develope...

Any chance there might be an ios port planned in the future. I ran into your game by chance and now I'm anxious to get my hands on it. I believe you would be able to get a lot of support from the forums in touch arcade, users are always looking for a good game(myself included). I wish your team luck...
