I am the developer of the recently released game "Plunk! the marble game" and I would like to invite everyone to take a look at it. Plunk can be downloaded from the App Store for free:

Plunk! the marble game is an accelerometer-controlled marble maze game that goes beyond rolling balls past holes and challenges players to think hard in order to solve each puzzle. The levels start off easy, with only one marble, and then quickly become more difficult as two, three, four or more simultaneous marbles force the player to come up with increasingly complex plans. Excellent graphics, smooth marble animation and realistic sound effects provide the great feeling of a classic toy.
There is a short video demonstration available:
