关于 HAL Protocol
Something is wrong aboard the HIS 01 Echo.
Your shift is over. The return shuttle awaits you in Compartment 9. All you need to do is walk there… but the corridor keeps sending you back to the beginning.
A loop with no end.
At first glance, everything seems familiar — but look closer. With each cycle, something changes: a missing object, a wall in a different spot, equipment moved across the hall. The anomalies aren’t tiny — but they won’t always stand out. Spotting them is the only way forward.
HAL Protocol is a first-person narrative experience focused on observation, memory, and intuition. No enemies. No jumpscares. Just you, the ship, and a looping mystery to unravel.
There is no time limit. Take your time, explore at your pace, and move forward only when you're sure. If something’s off, turn back. If everything looks right, proceed. Choose wrong, and the loop resets.
Can you break the cycle? Or will you remain trapped in the quiet heart of the ship?
