Part 1: Installation Note: You must have a jailbroken iPod. Make sure you have a wi-fi connection, then go into Installer, then to Sources. Tap the Edit button, and then the add button. In the dialog box that comes up, type: http://iphone.r4m0n.net/repos After that, go to Install, and scroll to the folder "iPhyisics". Then install the application iPhysics. You can then go back into this same folder to install level packs. Part 2: Objective The objective of iPhyisics is to guide the blue ball to the red square/star by using objects and gravity. Part 3: Controls Dragging creates lines. Dragging a perimeter creates a solid polygon object. Single tapping creates joints that you can hang lines or polygons off of. Double tapping will create small circles. To make a circle of adjustable size, tap and hold for a few seconds, and then drag to form a circle, with the radius being guided by your finger. To delete an object, the default control is "scratch" (draw a zig-zag pattern over and object, at least three turns in the zig-zag), although when this option is turned off this becomes a double tap as well. This does not interfere with the circles. Simply double tap an object to delete it. Some levels have the ability to use the iPod's accelerometer to change which way down is and therefore change which way gravity is pulling. You can also drag by touching an object and then dragging it. To pause, which brings up the Main Menu and Restart buttons, simply shake the iPod slightly. Restart will restart the current level you are playing, while Main Menu will take you back to the list of level packs.
