I'm waiting for an Android version
The web version is functional on android devices, and should be usable (if a bit awkward) on most mobiles and tablets. If you need to play it offline, it works fine with the JoiPlay app though you may need to alter a few settings, like making the game play in portrait orientation.
I might make an android port someday if I feel like I can improve on these options, but for right now, I think the game is playable enough on android for most users.
