The storyline isn't multi player?
Upon playing this it instantly became clear that something I loved in the arcade was playing the regular levels with friends.
This game doesn't do that. You can play against each other or you can play the story line, not both.
With that in mind it is still very fun to play, I enjoyed the warp squares that send you to random other places on the screen. Its nice to just use the Wii-Remote, that keeps it simple.
Worth the 5 bucks in my opinion! 5 Players at once woo-hoo!
