We do not support emulators and we can't guarantee that game will work normal in these, but we have official versions for PC (and Mac OS) on these sites!
At your PC:
And at your smartphone or tablet:
Therefore, we strongly ask you to don't use emulators. Probably, the poor performance of the game is connect with the emulator, and not with the game itself. If you still have questions about work of the game or you can't find links to our game on a particular platform, in what you're interest in - contact us through our support channel (Settings - Support or via email@example.com).
