One of the most pressing questions answered first:

We will start by selling the iPhone/iPod version for the introductory price of $4.99 (3.99 EUR) this May.

We will begin work on the iPad version right after that and make the app universal - i.e. update the game to run natively on the iPad as well. Once the app is universal we will end introductory pricing and sell the game for $9.99.

So if you buy early, you essentially get a discount on the version that runs on iPhone, iPod and iPad. We hope that’s a fair deal.
