The arena has arrived in OSX! Also, if you have multiple devices, your progress will be saved across from windows, allowing you to find glory in the arena from wherever you may be.
Along with OSX release comes some minor fixes, your cursor will now stay inside the window if you are unpaused in game - preventing you from accidently clicking on another program and coming back to an untimely defeat.
Along with this are some small fixes to the new options interface to make customizing a bit smoother.
Stay safe in the Arena!
