The only thing I had a slight issue with was that the story was predictable once the girl was captured. I could from that point have written exactly what would happen next from a perspective of major plot points. A grown up story would be preferred at some point. See Walking Dead show or game... don't cater to the idiot, give us a tough story. See Bioshock Infinite as well.
The slightly cliche story aside, the art and history was well done. The action was great. The tombs which are the namesake of the game should be a lot more complex than a single obstacle. I want to spend an hour in a tomb, being forced to use to torch for light, getting lost, then having a great reval/reward.
The only other thing I could fault would be the fast progression from mostly-believable to complete-fantasy too quickly at the end. Don't show the paranormal outright, make us wonder if the bad guy's plan would have worked at all or if maybe he was just effing crazy.
This is a really solid game and I look forward to a sequel.
