Some interesting results there. I agree with the top choices, though I would've liked to have seen Bunker control and Icarus Wave do better (personal preference, I guess).
Even if you didn't contribute, I'd recommend checking out the link above as Tom gives a lot of good feedback on how the games performed on his iPhone. The main issue it seems to highlight is that probably more than half the entries had sound related issues.
Anyway, one of the main things I learnt from the competition is that nobody ever reads the instructions (even if you have a big button marked 'instructions') so try to make games as easily accessible as possible (in game tutorials, and other helpers for example).
Well done to those who won, and also well done to those who took part. I'm looking forward to seeing some of those games develop into something considerably more awesome.
