I think you should need to develop for phone user. someone of my friend is trying to play a game of ro ghoul. but thats a big problem for us. we cant play because we are phone user.
Nobody on the Wiki is affiliated with the development or moderation team for Ro-Ghoul. As said before, porting such a game to a mobile device would be hard to accomplish.
I like the idea and also if sushi wants people playing the "copys"(not all tokyo ghoul games are copys) then make it one more gadget available but as the first comment states the wiki is not made by the devs nor the owner and its hard to make a game available for mobile devises but i do agree with you
