I am done! Woop! I got the non retina graphics working, and sent it out to a few friends. I decided not to submit to apple tonight, so that my audio buddy can get his paws on it and fix the audio track to be more nice.
One thing that really bit me is that when I changed the sizes for the graphics, I also had them tightly coupled to the box2d objects, so all the weights of things got jacked up. I did a quick fix and platform specific’d everything, but now the game plays slightly different if you are on retina display or not. Luckily there is a pretty big fun area with the mechanics.
The offer is still open if you want a build, just fill out this form, and I will hook you up.
