Ironically though, it's harder. Weird comment, I know, but you have to think about it. The description says to take regular breaks. That means that we didn't take too many breaks with Flappy Bird, all because we expected some kind of difficulty twist as we went on. The only difficulty twist was that of our patience to the simple controls, so we ended up being malefactors and just raging on the game, let alone the "Mario" pipes. We might as well rename ourselves "Malefor" because of that.
However, unlike Flappy Bird, this thing kind of KNOWS when you're getting good, so it just does a whole lot of random stuff to try to throw you off. If you saw the preview, some of the clocks had their ".NOON.s" in a different place than the norm (right, left, bottom; some even TURN). If you're really good, then you might see clocks switch places, as you saw in the preview, too. That's what I like about .NOON.
I'm not too sure about the other twists the game has, but if you think that this will be too hard, try playing Flappy Bird with moving pipes or piranha plants.
