I just finished porting my game Clickogone on my phone HTC Magic.
Many optimization have been made, but the result is not perfect. The bitmap provides much better performance against the vector.
I must say that I’m running Android 2.1 (Eclair ROM by Luo and Cyanogen) on a HTC Magic. In addition it is the beta of Adobe AIR runtime.
A lot of good things to come with the final version of Adobe Air for Android
