PewPew 2 is Gold! I submitted it to the App Store yesterday, and hopefully it will be accepted in the App Store within a week. It will be priced at $1.99, which I think is a very good deal considering the quality of the content :o
This month I did some beta testing on different devices (3GS, iPad), and discovered the performance on the 3GS was worse than on my iPod 2G! I lost a lot of time trying to find out what the problem was, until I finally found a post in a forum explaining that using timers to set the FPS is bad on the iPhone OS 3.0.
