Then even more years for iPhone, and finally now I'm playing the iPhone version on my iPad

One thing that strikes me is that the software itself has never seemed to change through all these versions

I don't mind the graphics too much (although new HD gfx would be awesome), but playability on iPad is a bit frustrating especially because I like to play in landscape mode.
You can swipe screen to move but it's cumbersome and only moves ones space unlike using the arrow pad.
Is this ever likely to be improved? or is the quest on its last legs

I really hope red shift give a little revamp for iPad. There's nothing else like it on app store
