Cyberpunk city + time loop + mystery and puzzles
The world is plunged into a “time fold” disaster, trapping humanity in an endlessly repeating 24 hours. The government launches “Project Paradise,” sending survivors into the virtual city of “New Eden,” where they must complete bizarre tasks issued by NPCs to earn “time crystals.” Whoever collects 999 crystals will gain the authority to restart the world, but nobody tells the players that the System itself is a lie.
