My previous product Space Chickens VS Angry Zombies was iPad only
this product is iPhone (but universal binary)
I am specifically doing it this way at the moment to test sales figures between the two platforms.
When I make a truly universal product the file size can be between 25-50MB and I start running into memory problems on the iPhone 3GS/4 devices (due to large retina bitmaps )
So I want to see if my sales figures are particularly different when I release versions that are suited to ipad or iphone separately and if I should be spending more time doing universal binary's with optimizations for smaller screens in the code or if this approach is better?
On the other hand it *IS* the retina 640x960 resolution so even if someone gets it on iPad it scales very nicely with the 2x button.
Basically this is an experiment for me.
Otherwise .. no plans for or against it right now just waiting to see what happens and open to adjusting in the future based off my results from this experiment.
