This is a great game, though have you considered making an android apk version?
Its a possibility. But it would require some time and effort to update the build system to also produce an APK. In the mean time, the game should work fine on mobile browsers.
Edit: I put it in the tracker https://bitbucket.org/VoidDirector/chosen/issues/6/create-an-android-apk-during-build-process so I won't forget about the suggestion.
