2D Java Game - Very Basic

I need a game - simple - in java that meets a said set of criteria. You must submit a modified version of the game which compiles, and contains the following features. The game should contain instances of at least two new subclasses of DynamicBody, significantly different from each other and from those distributed. Instances of at least one of your new body classes should be rendered with images. Body shapes do not have to align exactly with images but they should align sufficiently well that the look and feel of the game is not compromised. At least one of your new body classes should comprise more than one fixture. At least one of your new body classes should have at least one additional attribute with appropriate accessor and mutator methods. The game should be controllable with either the keyboard or mouse (or both). Your game should respond to certain collisions between bodies by changing the value of the additional attribute mentioned above. Add print statements to your collision handlers so that the changes can be seen to be happening. At least three game levels implemented as subclasses of a common class. On achieving certain goals within the game, the player progresses to the next level. There should be significant differences between the levels. A graphical interface that displays information (such as health, score, etc). Graphical User Interface controls (for example Pause and Restart buttons). At least four different kinds of dynamic body that interact with other bodies in varying ways. (These may include bodies presented for the first Milestone.) There should be two game features of your own devising. You will need to include a concise written description of the features, explaining the key coding challenges involved.
