The first Removr beta went out today. I wasn’t happy with how some of the pieces looked on my iPhone 4, so yesterday I cleaned up the graphics and added Retina Display support. Cocos2d doesn’t have built-in support for the retina display, so I had to check the scaling and load a @2x graphic every place I load any image. If you’re interested in seeing how I did it, I posted some code here.
I’m now working on making my level editor more usable. At some point in the future I may release it publicly and allow user-contributed levels.
