The time between

In a mysterious moment, the younger brother is caught in an unexpected accident that pulls him through time… awakening 20 years in the future.

The world he once knew has changed: ruined places, buried secrets, and events that have not yet happened for him.

Meanwhile, the sister remains in the past, unable to reach him physically. She soon discovers that every decision she makes and every puzzle she solves in her time leaves a direct mark on the future her brother now inhabits.

The game follows two characters across two different timelines:

1. The brother struggles to survive, understand what happened, and find a way back.
2. The sister reshapes the past with care—opening sealed paths, preventing disasters, and planting signals and tools that will appear 20 years later to aid her brother.

Puzzles are deeply connected across time:

A button pressed by the sister today may save the brother tomorrow.

A message left by the brother in the future may become a cryptic clue discovered by the sister in the past.

With every change, a new future is formed…

But altering time comes at a cost.
