F.A.Q

How do I contact customer support?

By email at support.hexus@gmail.com

I'm a bit confused by the special chips I have unlocked?

Take a look at the video section and see if that clears things up.
Also, touching them on the achievements screen reveals a help bubble.

What should I do if I encounter problems running Hexus?

Try restarting you iPhone/iPod Touch, and running the game.
There is a guide for restarting your device on Apple's official site.
