Hey, EponymousKay!
Since the game is made in SFML and is text based only an apk and html version aren't feasible.
Sorry.
I don't know if you can. There may be some way by converting the Linux version to an apk, but I'm not sure if that's possible. As I said earlier, at the moment it isn't feasible, but in the future, maybe. I'll look into it to see how much work it would take, but I assume a lot of behind the scenes changes would need to be done.
