This game is pretty good, you go around collecting cards and beetles, you get special moves and power ups for them. This game was really fun for me until one part where it is literally immpossible to advance without knowing katakana or hiragana (japanese language). You will like this game until you get to the part where you WILL get stuck if you don't know japanese, but this evidently means it will not last too long and I doubt you'll want to play it anymore.

Amazingly addictive
It shouldn't be good or interest you for long but this game is friggin class.

Brilliant!
You don't really need to know the Japanese language to play this game. Would be nice to know what people were saying but when you get moments of lots of speech you can just keep pressing B to get through it nice and easily and it usually leads to something which doesn't really involve much to get there. You use a Rock/Paper/Scissor system to fight using beetles. They all have their own special move which can be seen by how big it is on the screen when fighting. Just simply press either left, up or right on your D-Pad to choose which one you want to use. The beetles come in different forms and are actual real beetles. A great game that can keep you occupied for a long time ^^.
