Continuing upon the genre pioneered by Portal, Project Temporality is a third person puzzle/action adventure that defies the laws of time.
As Number 87, you have been chosen to explore the limits and possibilities of the TP-205 brain-stem implant. This grants you the ability to manipulate time, quite literally making it the fourth dimensions just as available for you to traverse and modify as the other three.
Going through a story of secret time traveling experiments near Jupiter, which has been ignited into a star, you will be tested numerous times. During the journey you will have to learn to shift your mental model of the world, so that you start seeing it in a different light, to find the solutions.
What really differentiates Project Temporality from other games about time manipulation is the freedom you have in your manipulations, we don’t restrict it to only working at fixed positions or certain time lengths.
The core element of PT is its time-line concept. A time-line is a separate copy of you active during a time interval, performing its own actions and interacting with the world at the same time as you. This is not a canned recording of static positions, it is a true recording of your actions. Which means that if you jumped onto a platform in the recording and that platform had been moved before that by another time line then the recording will jump and fall, not land in the air on an invisible platform.
So what is happening is true simultaneous actions from all the time lines and together they create the world you are seeing, so in a very real way you are cooperating with yourself. However, there are limits. Due to time paradoxes you can’t spawn a new time-line further back in time than your most recent one without deleting all the time-lines spawned after it. Because if you could then a time-line that no longer existed would spawn new time-lines and that paradox would destroy the universe as we know it 
Using these abilities you will uncover and solve numerous puzzles in a military testing facility located near Sedna. Playing through the story you will learn what is going on and why these tests are performed. And most importantly, what happened to Number 1 to 86.
– Cooperate with yourself over multiple time-lines
– Warp time around you to complete tricks impossible to mortal man
– Expand the ways you think about time and the world around you
