It's a nice little game. Not much depth to it, but it is pleasing to look at and has a sense of humor.
It is mildly confusing when you don't watch MLP though, and some of the humor is lost, though I suppose that is to be expected.
Also, this is kind of off-topic, but I kept thinking of Dragon Tales the whole time because of the name "Spike". Kind of distracting, but that's my fault, not the games'.
