Starting with this release, the client goes public and will use the same servers as the windows and mac client. Your games characters will be availabel on any platform but characters from the private beta are now unavailable.
In some cases fullscreen mode will set the resolution higher than your display can handle. Please ensure that you have the proper GPU driver and display detected correctly. If you have a problem, simply remove "conifg/unity3d/SpicyHorse/Akaneiro/prefs" in your directory and play in windowed mode.
