Hi Stoney, thanks about telling your first experience with the game!
I guess the way the input works is really strange, actually it is not about swipes, but you touch the character and the drag the screen around in the direction you want to move.
I really need to find a way to improve the controls, as currently it certaintly one of the aspects of the game that still needs polishing, but I will address that in a future update.
Also could you tell me about Retina support? I have heard that term before, but I don't really know how that works.
