In this game, the save system for the DLC is mostly independent from the base game, but there are specific "deep post" or "reversible" interactions to keep in mind:
Traditional game save systems store a snapshot of the game state at a specific moment, allowing forward progression but rarely enabling safe, complete reversal to an earlier state without loading a separate file. This paper introduces the Egis Reversible Game Save (ERGS)—a bidirectional serialization model that maintains a cryptographically secure, linearly versioned save history with full reversibility. The system guarantees that any saved state can be restored and that any subsequent forward actions can be undone back to the original save, akin to an infinite undo/redo but persisted across game sessions. We define the data structure, integrity mechanisms, performance overhead, and implementation patterns for integrating ERGS into existing game engines. A proof-of-concept case study using a Unity RPG demo shows less than 5% memory overhead and sub-50ms reversal latency. ERGS enables novel game mechanics (e.g., time manipulation without save scumming penalties, forensic debugging, and branching narrative testing).
On quiet nights he would sit with the shoebox between his knees and feel the paper edges as proof. He would read the names aloud that the app had once taken, practice their curves with his tongue until they tasted familiar again. He would not erase his saves entirely. The option was a modern mercy in emergencies. But he had found a different kind of courage: the willingness to live small mistakes into stories, to let consequences accumulate and, in their accumulated weight, make him human. egis reversible game save
Egis was not a god; it was a market. The first time he met the archivist who would become indispensable, she sold him back a Sunday afternoon he had sold on a whim. She watched him like someone cataloguing a specimen. "Names hold up poorly," she said. "Feelings hold up better if you index them with place."
The reversible nature of the save was a lie lodged in plain sight. If you could always go back and make another choice, consequences would be mere drafts. Instead the city had been reshaped to prefer permanence in the metadata of loss. People who burned their lives on Egis polished themselves into specters: smoother, less risky, forever burdened by the quiet ledger of what they'd traded. The option to reverse made reversals expensive. In this game, the save system for the
Like most visual novels of its era, Reversible utilizes a save system that captures the player's current state, including:
