Loads of fun to play
Extreme is definitely....well extreme and crazy hard, but doesn't make the game any less amusing.
The only complaint I really have about the game is that after a while it starts to hurt my wrist and hand cause it's hard to keep my wrist straight enough to play. I thought by now i'd need a wrist brace and thankfully I don't....yet. Also if you play long enough the strap on the grip breaks....well mine did and I'm sure it's happened to others, and mine is being held together with a friendship bracelet and velcro:P.
Anyway, I still recommend this game for anyone with a DS. It's worth the pain.
