I did a quick update of Planetary Defense. After testing it on an iPad2, I decided to leave it alone except for a few changes to the different levels of the game. After 60 bombs have been sent at the planetoid, enemy missiles show up. If the player can withstand this for a little while longer, they experience the “moon” level. There are no level changes after this just because I don’t know what would be good and also because I don’t yet want to write the path finding code for the enemy missiles to go around both the planetoid and the moon.
