So it has nearly the same issues with it as the first game did, very unclear on direction. Since I already mentioned my problem with the first riddle in the demo version, here is my problem with the prison puzzle. Why are you able to click the buttons if they don't do anything at all? Its just misleading in a game where you get no direction. You need to type in the letters corresponding to the colors of the wall objects.

Besides the puzzles being very peculiar and potentially misleading, the game overall doesn't make any sense. You time travel, then lose the thing that you just went through with. Then living Sphinx, and you shoot down a mummy and there is a bunch of technology in Egyptian temples or something. It just flowed so awkwardly with no improvement from the first game.
