The Sea Assault update with the point sprite changes has been released. It fixes other minor things too. The notes are in the support section.
Now, I'm already ready for the next Sea Assault update! ( Gasp ) I had updated before the iPad announcement. But I don't want to update spam users. According to the store documentation, new features need to wait one month and bug fixes need to wait at least two weeks. Only critical updates ( eg program crashing ) warrant an immediate update. The next Sea Assault update is going to put in some changes that got the program working on the iPad simulator -- as a consequence improve the odds on the actual device. I'll probably wait a couple of weeks. Perhaps, I'll wait until the next iPad beta software is released. But Apple said in public they'll start to sell iPads in 60 days. As I said before, the update jam is going to get more pronounced. This update is going to have view switching like Astroidica ... a cool animated effect.
I submitted the next Ant Planet update to the store with the iPad sim changes. This update will have point sprites for particles and some minor improvements. It will also have view switching to game mode like Astroidica has.
Astroidica just worked in the iPad simulator. There were no changes that needed to happen. No need to update Astroidica for now.
After these updates, things should settle down.
