We have recently submitted Ouch! Lite to Apple, and it should be available soon in the app store (for free, of course). If you are interested in Ouch!, but haven't yet decided it's worth $3, hopefully the Lite version will help you see why it's such a good value!
The Lite version has a few scenes to play, and a large selection of replays that you can watch from the full version. It does not have any character customization or scene creation available.
