Hello,

For now, our game is only supported for Windows 10. We are focusing on improving the game for now and are not currently supporting Windows 7, 8, 8.1, etc. If you are playing on Windows 8.1, then I hope it works for you fully, but I can't say that for sure.

Regarding future OS, at this time, it's not currently planned. We are working towards making the game better for Windows 10 and soon future release on XBOX.
