Nice.
I loved it, there is one thing I say, before reviewing it fully. Could you please make something that teaches japanese on flash (like use voices, words & symbols?) x3 I really want to know it, more so now.
Anyways, I'm sorry you want to take it down but:
Graphics - Nice graphics, very cartoonish, suits it.
Style - I loved it, dunno why, just did.
Sound - Nice japanese (and squeeks), nicly subbed aswell.
Volence - Yeah, I don't like violence, unless you do it xD
Interactivity - 1 button, play.
Humor - Exceedingly funny in so many ways. Well, I was smiling all the way through.
