Will you be porting this to Android at all?
I don't currently have any plans to, but this is mainly because people seem to do it for me. I think there's an android version of 0.2 floating around on the internet at the moment, but I don't know how well it works. I'm not really sure how well 0.21 would work on android even if I did port it, given the nature of one of the sections in it, but if I find out there's a 0.21 port somewhere, I'll link it here. (Assuming I can verify it doesn't contain malware or whatever)
Maybe at some point, but it's not a focus. It's not as simple as just pressing the "build android version" button. There are whole sections which would most likely need to be reworked, and a bunch of screens that would need to be redone. I will say though that if I ever get to the point where I'm making enough from this to go full time, I'd probably hire someone to do it.
