The iPad version is cheaper for a number of reasons.
1. It has fewer features, due to the limitations of the device. Most notably, it is stuck at a low (1024x768) resolution and there are no keyboard shortcuts.
2. Since it is being sold by Apple, it is subject to the rules of their system. Most notably, there is DRM, and we can't give refunds through iTunes.
3. There is no ability to modify the game.
4. There is no demo.
5. The iPad version will always come out several months after the Mac/PC version.
Ever with the lower price, it is still one of the most expensive games for the iPad by a fair margin. We are charging pretty much the highest price for the game we reasonably can, in part to keep from annoying other users.
We're sorry if anyone is angering by this. If you think about it, I think you'll see that the pricing is fair considering all the factors and that, more importantly, there really isn't much we can do about it and function as a business.
Finally, I think that asking for a refund for a game that you purchased, played, and enjoyed and obtained at a fair price (and yes, $25 is a fair price for PC/Mac Avadon) is, well, it's pretty shady at best. We will honor the commitments we made, but I like to think that our fans, annoyed or not, would not take advantage of a small indie developer in such a way.
