Unfortunately we still have to wait with gameplay videos. We are working hard on some finishing tasks. I hope, we can show more next week. Funny fact: it runs smoother on an iPhone4 than on an ipad.
Yes, but not so much less. It supports retina display (looks extremely "fancy"), so it has 640x960 while on ipad 768x1024.
The game is Processing for the Appstore now. Should be "Ready for Sale" in a few hours. We have set the release date to Wednesday June 29. though. So it will be available Wednesday worldwide. We want to start with a whole day and try to avoid the whole Appstore syncing mess. I will post in the games section with direct link, when it is live.
