Paul Pridham's Saucelifter (a loose remake of Choplifter on the iPhone) is available as a free download for the rest of the day, which is normally priced at 99 cents (as indicated by Joe Larson of ASCIIpOrtal fame in the video shown above). Best to grab it quickly before the offer expires.

The developer is currently hard at work porting Sword of Fargoal for the iPhone, so keep an eye out for that as well.
