Now, this is all in the creative license of the developer, but it would have been nice to have multiple options for solving some of the more complex puzzles. The aforementioned time constraints, and even the puzzle layouts, sometimes seem a bit unfair, with there being a lot of goals you'll come up short on, just because you haven't nailed down the exact, to the letter, way the game expects you to play it. However, not everything seems to work quite as nicely. The levels themselves are a bit dull, but in general it all works fairly well. The artwork is absolutely adorable, with the astronauts looking akin to game board pieces.
It's a nice goal to remain within, as the player is given restrictions, but won't have to worry about long loading screens between failures. It may sound like it would be possible for the player to just drive time forward till they figure it out, never having to rewind, but there is only a finite amount of time to work with. Because you'll have to drive time to a certain point, then manipulate the environment more before going forward more, the player is always in contact with their interface, essentially the mouse and screen. The controls for time movement may sound absurd, but they work so well it almost feels like any other control scheme would be less than. They must turn arrow panels at certain points in the level, then drag the mouse up or down to either move time forward or back. To be clear, the player's involvement is at the absolute minimum. This happens when the mouse is dragged down the screen, allowing absolute control of the great hourglass. Instead, you will manipulate their path to guide them into their respective spots. The astronauts are not physically moved, as their path has already been determined. Causality is about guiding astronaut-like people to a panel that is the same colour as the one on their designated suit.
