An absolutely Brilliant learning tool!
I own the prequel and the new features turn a really good program into an amazing one.

The new diagrams to show what you did wrong when drawing a character are really easy to understand. Though if you draw a stroke backwards, say right to left instead of left to right, the diagram is sometimes in the wrong place. Doing the strokes as the animated diagram in the program does avoids this entirely.

The new readings section is brilliant!
It gives the ON and KUN readings and many examples of words using the kanji.

The testing in the game is great though some more knowlege of japanese is needed to do them with much ease.

This is a must for anyone learning kanji.

Great learning experience
This is a great learning tool, if you at least can read hiragana. I bought it because a few months ago I started learning Japanese.

When you first boot the game it asks in which grade you are (from the grades of Japanese school, 1 the first year to 6 the sixth), then it gives you a level test so that the game can figure out where you should start, after that it shows the normal menus for hiragana, katakana and kanji.

It has all joujyo kanji (1945 kanji, including meaning and way of writing them correctly) along with hiragana and katakana in order for the user to learn how to write them correctly.

For example, in hirangana, you write the symbol for "a" and then tapping on "correct" button it gives a grade between 0 and 100 (being 50 a "pass" and 100 "perfect"). What's more interesting is that the sotware tells you the spots you got wrong and how to fix or improve them, it's like a Japanese teacher on the go.

To sum it up, if you are learning Japanese; I recommend you to get this game, it really helps a lot.
