More years than I care to remember and lots of bugs it seems.
So basically, this has happened four times now. I've found that on the PC version, when I load a new chapter or continue from my previous spot the game will finish loading the level, prompt me to hit space to continue. At this point, the game appears but I have a menu mouse cursor on screen. I can move the cursor around the screen, it has no effect on my character movement and the mouse buttons don't do anything, neither does the keyboard.
From here, if I press esc to try to get rid of the cursor all my controls lock. Everything. And the only way out is to Alt+F4. Obviously the game has only been out for an hour or so, so even searching Google or looking in the obvious places isn't helping. Anyone else experiencing this?
