Meh!
This is yet another sad case of a great game that has just been left to languish by its creators until it no longer even runs properly.
There is a "newer" Robot Unicorn Attack that is probably what the creators want you to buy, but it pales in comparison to he original. The graphics on this version as less complicated but better for it, as is the game play.
Considering the p creators have no financial impetus to fix this "old" one I guess it will eventually fail completely and have to be deleted. At least it doesnt ask for Game Centre to be turned on anymore.
