Echoes of the Light

In the near future, humanity discovers a strange phenomenon.

A Quantum echo - a burst of light emitted that vanishes almost instantly, but can be resurrected.

Play as Kaela as she unravels the secrets locked inside these echoes.
Make choices, face ethical dilemmas and uncover quantum enigmas.
Unlock the secrets hidden in the memories trapped within the echoes.

And decide who gets to wield this quantum power!

Key Connections to Quantum Physics 
This game is intricately related to quantum physics through its core themes, mechanics, and narrative elements. At its heart, the game explores fundamental quantum concepts like superposition, entanglement, and the nature of observation and reality. 

Quantum Echoes as Narrative Devices:
The central gameplay and story revolve around “quantum echoes,” which are faint, unstable quantum states preserving fragments of past events, memories, or consciousness. These echoes embody the principle of quantum superposition—existing in multiple, overlapping states until observed and decoded. 

Alternate Realities and Timelines:
The game introduces alternate timelines derived from quantum branching, reflecting the many-worlds interpretation, where every quantum decision splits reality into divergent possibilities. The player’s choices affect which timeline survives, mirroring how quantum outcomes depend on measurement and observer interaction. 

Quantum Memory and Information Theory:
The gameplay incorporates quantum memory technology concepts—the encoding, preservation, and decoding of quantum states, representing data beyond classical limits. This is linked to real quantum computing efforts where information is stored in quantum bits (qubits) and subject to delicate coherence and decoherence.
