I spent quite a lot of time there, found 2 fires, a book, a scull and then got lost. The tomb is too big. It's just a big dark maze. I think you should have added a punched bag of salt strapped to the player and leaving a trace behind so the player would know they have already explored this part. I liked the atmosphere and lighting especially. You acheived quite a lot. It even has an inventory system. Great job!
