Mobile first please
(being a mobile player i need to take the other side, sorry) I think that PC would be a better idea, because they already have controls down for it, and it costs money, so its only fair to have the people that pay for it, to have it first, unlike the people who get it for free. Plus, on mobile, the joystick is so annoying to use with 2d, and they could improve it a lot, so mobile should take more time than a copy and paste, unlike PC, having said that, mobile would dis improve the game quite a bit.
