Here's the promised update about the first 10 days with iAds:

Total Downloads of "100 Chambers Free" so far: 25145After releasing the free version, the sales of the paid one dropped by 20-30% but are steady there.
I wish Mochi-Ads would have such a nice eCPM

then there would be a lot of flashgame millionaires

I hope the insights are helpful for you.
The games also ranked pretty nice in the App Store in 2 countries:
GHANA - IPAD(PAID) - GAMES/ADVENTURE | FRANCE - IPHONE/IPOD(FREE) - GAMES/PUZZLE |

Well, what can I say? I hope this trend is continuing with the upcoming updates (there's still 60/100 levels missing)

Cheers!
