Mine is broken I cannot play it at all. I cannot access the button configuration when I try to go down It will not allow me and it exits out of settings on the main menu and in the game which means I cannot assign controls on my keyboard or to a controller at all. Also, I cannot raise my weapon at all or run I can only walk and interact with things since my controls are messed up. I have tried the f1 and f2 fix, and deleting and re-downloading the demo, and the issue persists. I seem to be the only one with this issue.
Here is the thing. I have tried that many many times. alt+f4 just exits me out of the game, and I can't even exit the game from the pause menu as I cannot move down the menu even with the keyboard as it kicks me out of the pause menu when I press down (and out of any menu). By this point, the game is broken for me. And no amount of "F" commands or re-downloading will fix it. I think I'll just wait until the official release to play it so, I won't have any issues. I have very high hopes for your game and I know it is going to be good.
