Hourglass is a narrative puzzle game based in time manipulation and cloning mechanics, most similar to games like Talos Principle and The Swapper. You play as a girl trying to find her father amongst ancient Egyptian ruins, but quickly you discover technology way more advanced than expected, allowing you to create a copy of yourself. This is the primary mechanic that carries the 4 hour long adventure. The game is a perfect length for its genre; mostly linear, with a few areas which give you the ability to solve in whatever order you'd like. Mainly the various puzzle rooms do a great job at communicating the goal you are trying to reach and what is tricky about each room. Where many of the puzzles could have come down to rote trial and error, being creative and messing with possibilities becomes much more of Hourglass's fascination, resulting in a few brilliantly clever sequences. The mechanics don't expand much, only adding an extra wrinkle or two to the complexity, but this helps the difficulty not curve too greatly. The story was generally pretty generic, and didn't leave me with a particularly satisfying conclusion, but I was pulled in more anyway by the fun puzzles and interesting world design. Hourglass is a fun stop-gap puzzle game that will give you a good dopamine rush if you like similar titles in this genre, which I reccommend for any fans of the setting of ancient Egypt or creative problem solving.
