The game crashed or hung?
- You have updated to the latest version of Touch Physics
- Please switch "Statistics" to OFF in Settings / touchPhysics
If the above does not solve your issue, please note the following:
Occasionally a game may refuse to launch, hang or crash. This applies to many iPhone applications especially larger ones such as this game and it is due to memory constraints on your device.
To free up memory, simply reboot your device by holding the Power and Home Buttons for 10 seconds.
If this is happening frequently, it might also be due to background applications like Mail running, which can be solved by temporarily switching off Wifi and Cellular access in "Settings".
