The game starts with kanji "meanings." It teaches the kanji in groups of similar ones so you learn to distinguish them and can actually pick them out instead of being unsure if the kanji you see is the one you learned. The individual kanji "meanings" are intended more as mnemonics, to allow you to distinguish and name them, but they've still been quite usefull for my other Japanese studies. After you learn to type kana, you use them for the readings part, where you learn the on and kun readings. I think learning the meanings first is better, because there are many readings, and knowing the general meaning of kanji is immediately rewarding since when you see them in text you can get a feel for what the text says.
