What happens when a time machine goes crazy? Avoiding dangerous time paradoxes, your only hope is to repair the machine between the time rewinds.
The antimatter instability causes a black wave of time-distortion, bringing you back in time: each time the cyber world will be populated by yourself and your past alter-egos.
They will replicate all the actions you previously did, and being seen by them will cause a mortal time paradox.
You will have to solve mini puzzles to retrieve the gears to repair the time machine, and to survive to your past-egos in a puzzle game with yourself and your own mind.
