Funny that you ask that. This project did actually start out solely as an mobile game that was played in exclusively portrait mode. Heck I have an old Android build on my phone right now.
I only recently converted everything over to 16:9 and put more focus on playing on PC so it could reach a wider audience. I wasn’t sure how things would fly if I introduced this as a game that you could only play on your phone. I’m not sure how most feel about playing a fatty game on their phone, heh.
But to answer your question, if the interest is there to put it on mobile, I can most certainly try. A decent chunk of the framework for touch input is already there aside from camera controls. So possibly once a pc version gets put out, depending on the feedback on that, I can start working on a mobile version if the public interest is there.
