So I have run into one issue. I have reached a point where the game won't progress in the text. I am in chapter 6 where Lang states "Oh no. I'm taking the bastards who forced me to ruin with me." At that point the background goes black and regardless of what I press I can't proceed. The game isn't frozen as I can still press the menu button. I have tried restarting the scene and exiting the game and restarting it but the same thing happens.
Sorry to hear about your problem with the game. That's odd since this is a first bug report on something like this. We will definitely look into this but meanwhile please try to quit the game, then start a new game, exit back to main menu and then restart chapter 6.
Thank you for the suggestions but sadly the issue still happened. I also tried downloading the Windows version of the game to my wife's system that runs Windows 7 Pro SP1 and bringing my saved game over and it happened there as well so I think it is either a corrupt save file or an issue needing patching. It has happened on Solus Linux as well as Windows 7 Pro 64 so it's not OS specific. I will start from scratch and see if it happens again.
