I already sang the praises of Zeboyd Games' Cthulhu Saves the World when it appeared on iOS: I think the world could use about a million more of these kinds of classic Japanese RPGs (and Zeboyd's latest title, Penny Arcade 3, just arrived on the App Store.) But I also admitted that playing Lovecraft's God of Madness' adventure on a touchscreen wasn't ideal. The movement controls, specifically, threatened to rub the print off of my finger with all of the swiping I was doing.
If anything, that makes CSTW an even bet
