Boo. – What's That Tune? Review

Almost automatically makes me have to upgrade to play. They say you can play multiplayer without upgrading but I don't know anyone else playing it so I just deleted it. Granted, it's only a dollar but at least give us a taste of it to play by ourselves to decide to upgrade or not. I don't like playing against random people.
