The Mysteries of Akh

You play a scavenger who discovers an old rune granting you access to an ancient pyramid. You decide to dive into the tomb expecting to find a concealed treasure. Moving from one room to the other by resolving puzzles using pipe pieces, you will eventually reach the Royal chambers. It will turn out the lavish treasure you expected to discover does not correspond to the one that you will unravel in the depths of the pyramid.
