Well, the original version was better, but "Fruit Ninja: Puss in Boots" is still provides an entertaining and enjoyable fruit-slicing experience. This one does have some different levels and modes, so that's cool.
If you could only have one Fruit Ninja game on your phone, I'd tell you to keep the original. It has a lot more to offer. But Fruit Ninja: Puss in Boots is well worth playing, even if it's more expansion than stand-alone.
