It's not that easy. If it was, we would've fixed it a long time ago. The game simply wasn't made with the intention to run on mobile devices. It means we'd need to overhaul the entire game from scratch so it runs smoothly on mobile devices. We simply don't have the resources and the experience to do it.
Now if there's anybody who's willing to try, by all means. As it stands, we're spending our free time creating the sequel. We're doing our best, and that's all we can do.
