WTK Episodes (there are 3 and 4 is on the way) is going pretty on mobile platform (it has 3 mln downloads overall), but doubt that I need to make PC version. Its because mobile versions is free-to-play with in-app purchases (and time limits), and this is impossible on PC, so PC version is free (1st episode) and paid (2nd).
And in general, it is interesting to see, what is PC indie market comparing with mobile.
