What happens when a time machine goes crazy? Avoiding dangerous time paradoxes, your only hope is to fix the machine between time jumps.
Antimatter instability causes a black wave of time distortion, returning you to the past: each time, the cybernetic world will be populated by you and your past alter egos.
They will repeat all your previous actions, and falling into their field of vision will cause a deadly time paradox.
You will have to solve mini-puzzles to get the gears to repair the time machine and survive in the past in a puzzle with yourself and your own mind.
