Hi guys,
If you're curious about how we managed to port a game such as Leap of Fate to Mobile, here's an in-depth article we wrote on the topic for Gamasutra.
http://www.gamasutra.com/blogs/MattieuBegin/20161003/282581/The_Challenges_of_Developing_for_PC_and_Mobile_Part_1_Controls.php
This Part 1 is focused on the controls, and Part 2, which will appear soon, is about graphical optimization.
Hope you find it interesting.
Matt
