Bring 16bits back!
You'll discover some secret levels, that are really secret so One's might finish the game without finding any of them, i've played some levels over 10 times to find everything.
the gameplay is extremely solid with simple and effect commands, also Wario has lots of moves.
There's also the motion commands, which work well and never tires you. You can punch the ground by pulling the controller down and shake the remote to get coins. You can also aim by tilting the controler.
The music is absolutely classic, i might just burn a cd just to hear them when i'm not playing. Sound is also very solid: when Wario stars a level he says "let's goo!" "rock'n roll!" and other funny things.
Yes, the game has great sense of humor, even in the items description. There's so much detail in this game, you won't find anything out of place.
Just don't miss the game, it is fun, it is beautiful, and it works great!
