Echoes of Time
RPG Game Demo
Echoes of Time is a narrative-driven sci-fi mystery RPG that blends time travel mechanics with emotionally-driven branching storytelling. Players take on the role of Lin Xia, a quantum physicist who, after the "Crimson Mist Disaster" destroys the world, uses her own time machine—the "Temporal Anchor"—to send her consciousness back to 30 days before the catastrophe, uncovering a conspiracy where no one can be trusted.
The game employs a three-act progressive structure: Act 1 establishes emotional motivation (the sister's sacrifice), Act 2 unfolds the mystery investigation (who is the real culprit), and Act 3 ties together all clues and presents the final choice. Core gameplay includes evidence collection, NPC trust value management, and state reset through time jumps. Playtime is approximately 6-8 hours with 3 branching endings.

World Setting
In 2242, the "Crimson Mist Disaster" turns 70% of the population into monsters—caused by a deliberate accelerator malfunction. Lin Xia's "Temporal Anchor" sends her consciousness into her past self (53% success rate). The narrative alternates between post-apocalyptic ruins and pre-disaster daily life, driving the mission to "correct the past."
Plot Design
Act 1: Lin Xia finds dying Professor Chen, learns the disaster was man-made. She battles her mutated sister, then activates the time machine.
Act 2: Lin Xia returns to 30 days before the disaster. She investigates three people—fake-helpful Zhang Mo, info broker Sister Ai, cowardly insider Li Zhe. The truth points to "The Purifiers."
Act 3: Lin Xia convinces young Professor Chen to stop the experiment, confronts Zhang Mo. The disaster is stopped, but she must stay behind to repair the timeline, watching her sister leave as she fades away.
Core mystery chain: Chen's dying words → Ai's intel → Li Zhe's breakdown → Zhang Mo exposed. Every clue leads to: your ally might be your enemy.

Map 1:Research Lab Ruins (Prologue)
Map 2: Pre-Disaster Research Lab (Act 2)
Map 3: Particle Accelerator Control Room (Final Boss)
Opening scene. Players enter, move through ruins hallway, find Professor Chen pinned in Sector B. After his deathbed scene, go to Central Plaza to battle mutated sister, then enter Time Machine Room to complete the jump.
Act 2’s largest map uses a hub-and-spoke structure: Central Corridor connects four areas—2F Lab (Li Zhe), 3F Office (Professor Chen), Security Dept (Zhang Mo)—plus routes to Archives and Underground Passage. Players can investigate freely. Each NPC’s room carries narrative weight. After collecting all clues, head through Underground Passage to Sister Ai’s hideout for key intel.
Final scene: Accelerator core (circular, red pulsing light). Enter from bottom, final save point. Boss battle starts in Central Hall. Lin Xia at Main Console, Zhang Mo in center. Two routes: Combat → crack three quantum locks on console. Strategy → pre-install broadcast gear, expose Zhang Mo to the city.
