I tried the app today (on a borrowed iPad mini) and thought it was really very well executed ... except for all the visual noise in the background: umpteen kinds of "paper", ripped paper, torn paper, folded paper, burnt paper, Chinese art, and especially that plasticy woodgrain effect.
I just found it distracting and would have very much preferred a plain white background (or maybe a subtle suggestion of paper).
Is there any way of turning that stuff off?
