It worked fine on me

People seemed to have lag issues and I can see that, but not even close to cause problem.
Although there was a Raystorm, I decided to get this instead because of soundtrack- I like Rayforces soundtrack better.
And Rayforce is also known as most beautiful pixel-graphic on the arcade at that time. Entering atmosphere, breaking ground... Gorgeous.

But you see, Im a big retro fan. I would prefer to play pixel graphic than clean realistic 3d. And not everyone is like that.
The sound, graphic seems fine, but only with original graphic resolution. Once zoomed in, it cause some problem.
But these can be solved easily by rebooting your phone, as it DESCRBED on description. Maybe people just need to take time and read whats on there. I mean, its there for a reason.
