Hello! Well, the android port is not official and isn't supported by me. I don't know where it sits right now content-wise, but the official build currently has up to 6 chapters (0, 1, 2, 3.1, 3.2, 3.3, 4). If it does feature more content than the android port and you'd like to play it on your phone, I suggest using that same application another user mentioned below. Joiplay, I think? That might work for you, too!
