Very good immersive experience! Love the dithering effect employed here - it did well to add to the atmosphere of the game. Sounds were minimal, but for a game like this, it is the perfect choice! I was a bit lost in the obelisk part(I honestly thought it was some kind of puzzle involving the Sphinx), but I managed to get past it after a bit more exploration. The cursor in the middle was a bit distracting and would have preferred if it was hidden, but this is simply a nitpick.
