Unpleasant Horse, the debut title from experimental PopCap off-shoot 4th & Battery, is now available on the App Store.
It's a free universal download for both iPhone and iPad in which you have to hop the titular nag from cloud to cloud while stomping other ponies into a set of meat grinders on the ground below.
It hasn't been a smooth ride for 4th & Battery's first game. Apple rejected the title on its first pass citing "mature content".
4th & Battery then promised to resubmit the game at a higher rating, which it appears Apple is happy with.
