Its strange only thing kill you is the water. Is interesting puzzle but need some direction and hints what you need to do. Its frustrating when you open one gate and nothing there. I feel the next key need to be in the new room you discover or something give you direction in what area the keys are. Spend all this time and the ending is disappointing Just BLOW the pyramid :D. I like the game you need to expand this have potential! And made some lights in the tunnels its dark there.
