veil the big secret of ancient Egypt. Besides offering an ancient world to explore, Hourglass is mostly about solving various puzzles with a unique core-mechanic. Your ability allows you to record your actings for a certain amount of time. After that, time winds back to the beginning of the recording and a copy of yourself appears, repeating the actions. On your adventure, you will have to use this ability in creative ways to get through various areas filled with difficult puzzles. Although completing the Story itself might take only about 4-5 hours, there is way more to explore. Completing 100% of the game will take much longer.
