Astro Emporia will be making it's way to some new platforms soon.
The version for Mac will be the same as for Linux and Windows. The Mac version is currently being tested and should appear on Desura soon.
A version of the game is working on the Android without Error but the interface is currently undergoing some changes to make it more suited to the small screen. Some of these changes should filter back to the next version for the Desktop game.
Upcoming changes after these releases :
Extended game mode - This will double the turns allowed and introduce tiered solar systems.
Main Menu changes - Total redesign of the main menu to allow for the new game mode and (hopefully) make it nicer :P
Cheers to those who have purchased the game so far!
