Posted on 15 June 19 at 13:27If you use a good walkthrough (like the video found in several TA solutions), it’ll take you between 2-4 hours. Without a walkthrough it’ll be even longer unless you’re amazingly good at puzzles. The game hasn’t been patched and it’s doubtful it will be because it’s been a while since these issues were first reported. One workaround that has worked for me is to play an entire area in one sitting but I haven’t tested doing a second area in a second sitting yet. Also this method won’t get you the final achievement for seeing the end of game cutscene. So if you don’t have a few hours to dedicate to a good but (in my case) mind numbing video walkthrough, I’d wait on starting this game.
