Key Features
Kinetic Visual Novel - In this predetermined world that we live in, there is no free will. We don't afford such a luxury.
Cyberpunk setting - Dive into a futuristic cyberpunk dystopian world where everyone resides inside a megastructure ruled by a authoritarian regime.
Temporal War - Fights partake in ways never seen before, with characters inverting, completing paradoxes, and sometimes even causing causal loops.
In this aimless darkness of space, this world that we’ve been placed on continues to turn.
This world was fated to end since its inception.
And on it, we mortals wait for its inevitable end.
To travel through time, one must be willing to leave everything behind and be self-centered enough to change one's own fate.
And changing one's fate means going against the very same God who placed us here.
"The grandfather paradox is impossible. In fact, all paradoxes are impossible. The Everett-Wheeler-Graham or multiple world theory is correct. All possible quantum states, events, possibilities and outcomes are real, eventual and occurring." - John Titor
