Agh! I'm sorry, I didn't realize it was a GBA game for some reason >_
I can't try it out. But I just happen to be on the phone with a friend who has played with it as I type this!
SOOO..
She says it's VERY hard to play and says it's not a traditional game.
It plays more like an actual Mutsu and doesn't do much.
Words will pop up that you can't understand.
You get 3 buttons to push (like original Mutsu)
1 button feeds, takes you to another set of button that does other things.
Basically it just moves around and reacts. Goes through it's friendship levels.
It's best to just get an actual Mutsu.
Then she goes on to talk about another friend of ours who is much better at figuring out the Japanese games and this other person gave up on the game. So I'd not recommend it at all.
I could not find any game play vids. It would have been nice to see. I bet it's cute but just not easy to figure out at all.
