4 out of 5 stars, pretty good project!
33 gave me pause but 39 made me actually stop and study the board for a while.
This was quite fun but suffers from one flaw most of these games have. Once you figure out a puzzle, doing it again and again and again - sometimes up to dozens of times in some games - especially for a single level just makes it tedious, not fun.
Take the first image to the right: There are five sand (? sandrock?) moving puzzles. Three are identical. Many levels use this conceit.
Secondary flaw is the sheer amount of walking some levels have. Level 40 is one of the worst. Back and forth the length of half the level is - once again - tedious, not fun.
I do not mention those to say they need to be fixed. These are normal issues and would be difficult to avoid. I feel the game should be left as is and and changes be made to a sequel, if there is one. (The top, right corner screams to me that "your princess is in another castle" and there are seven more chapters.)
Minor improvements I'd like to see include visual changes to the stairs upon collecting the final ankh and a visual change if a door can be passed (player has a key).
