Graphics are simple, yet, pleasant to look at. How to cross the rocks near the end had a WOW effect for me. Also, the free ride to the tower was amazing. Sound effects are good.
Game play is interesting and challenging. I had used the walk through several times in order to progress. First, I missed a few clickable spots. Second, I had trouble solving some puzzles because certain clues were too vague to be noticed. I totally missed the clues for arranging the coloured rocks as well as unlocking the cave lock and the lava switch lock. Also, I only got half of the symbolic codes inside the tower.
