This minor update fixes the issues people were having with the game not starting on the correct screen when played on a multi-monitor setup. The game will now remember the size, position and screen the game was last played on, so it should start up exactly where you left it. Please let me know in the forums if you have any issues with it.
Please note there is still an issue with using mouse controls when the game window is on anything other screen than the primary one. For some reason the mouse cursor is able to exit the bounds of the window which it shouldn't be able to do, but this appears to be an engine bug, so will probably take a bit longer to fix than the other stuff.
