A pinball game from Little Wing... if my memory is correct, they made Loony Labyrinth too, a game that I loved when I got it. Sadly, that one hasn't made its way to iOS yet. Reasonably priced at $1.99 (in the USA App Store) and just updated today to support the iPhone 5's taller screen. Discovering this app makes me very happy indeed. 
(Added bonus: I saw Pinball Crystal Caliburn 2 from the same developer, picked it up as well... and still had $0.06 left over in my iTunes account.)
