It says "Requirements: Compatible with iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad. Requires iOS 6.0 or later. This app is optimized for iPhone 5." but it didin't work on my iPhone 4.
completely misleading. I would have thought this would be set in the metadata for the app correctly. Android devices actually prevent you from purchasing and installing on incompatible hardware (I have an Android not an iPhone, my wife has an iPhone 4).
I was quite excited when I saw that Limbo was on iOS but disappointed with the high minimum requirements.
