A simple story of a simple girl who discovers that she can simply leap thru time. But instead of using her powers for good, or even for evil for that matter, she uses it in a manner that we all wish we could if we were so magically endowed (especially if we were her age): to make up time when we were late, to retake exams we didn't study for, to get to our favorite snacks in the fridge before our annoying little siblings got the chance to polished 'em off, etc..
Which all leads up to a simple coming of age story that is as simply & beautifully told as it is simply & beautifully animated.
Simply put, simply beautiful.
