T is of course a common challenge spot for players. This was one of the reasons we wanted to open up the rest of the levels after the tutorial, so you could try any level you wanted (of course this isn't really communicated well to the player), and in hindsight we probably should've put OX before IT, but the concept of "difficulty curve" is more complex when you're bound by the artistic interpretation of what makes up a letter. This is something we will certainly explore more carefully for a future update though and thanks so much for playing the game!
