Very, very good! Some notes:
!!! Consider moving the die roll outcomes to the back of the manual so it can be easily accessed as a reference !!!
What happens if you are suppose to gain an altar and all tokens have been claimed? Be explicit.
What happens if a player trades in an altar on a space that awards altars? In your “Crossing The Sea” example, if a player trades in an altar, they will get two back and 6 points. Effectively gaining an altar and a lot of points! You can fix your “scoring” text to be more clear by by saying “double points” instead of scoring. I think that’s what you mean, but you’re being loose with your phrasing. It wouldn’t hurt to be explicit that you never gain an extra altar in this situation.
Also, and I know it's very unlikely, but you should probably be explicit that you cannot have negative points.
