A bit of an update...
The saves work perfectly but unfortunately for me it is going to be a long time before I can finish this game. I needed the save for after the elevator fight where Farah keeps dying so I got that and opened it up. I played that level and I go to a cutscene and save. On to the next level.
I wake up and no longer have the dagger. What that means is that there is no REWIND

Now we have to play through the level flawlessly while fighting nasty bats. I gave up on that level and loaded up the next one.
Same thing...still don't have the dagger. Not a problem, I move through the level and then I get to a tall area to ping pong up the side. I'm a good ping ponger so should be no problem. Wrong. As soon as the camera view shifts, I fall every time. I am wondering if I need to switch arrow keys when the camera shifts?
I got tired of starting this over and over again and loaded up the very last level. The boss level. Alrighty then! I do battle with the bad guy and defeat him. Now Farah seems not to know me and will not believe my story and how they love each other.
I will keep plugging away at these missed levels because I want to see the story but I think it might take me awhile, lol.
