I played this quite a bit with my son today and we had a blast. The difficulty curve is a little steep with objects at the top of the screen coming pretty early but he got the hang of it pretty quick.
The controls work well with the mic except if you get the two players too close together and then both mics pick up both players.
The graphics are simple but are clean & work well for the game.
If you have kids who want to play but can't handle a controller yet this is well worth checking out.
