I can look around on mobile but I didn't figure out how to move. I tried tapping and double tapping everything but nothing happened. Only some "object is out of reach".
You can move by swiping your finger within the purple-like circle at the right part of the screen. That circle simulates a joystick for character movement. And you can look around by swiping anywhere else on the screen!
Agreeed. I finished the game on mobile ;) Though the story could use some work !
