Rebuild a dead techno-gothic empire in this dark idle clicker.
You are the last sovereign of the Hollow Crown, awakening in the ruins of a once-great empire. Summon ritual servitors, fire up the hematic pumps, and channel Blood Fuel through the shattered circuit. Decode Grave Data from ancient crypt archives, issue Royal Decrees for power surges, and ascend the throne to earn permanent Crown Sigils that carry across every run.
KEY FEATURES:
— Dark Fantasy Idle/Clicker: Click the reactor in the Dungeon to damage twisted foes and harvest Blood Fuel, or let your 6 generator types produce resources passively.
— 12 Upgrades & 12 Research Techs: Enhance your reactor, industrial base, and forbidden archives through a branching progression tree across Reactor, Industry, and Archive categories.
— 4 Royal Decrees: Issue timed commands for massive production surges — Extraction, Tribute, Silence, and Dominion — each with unique effects and cooldowns.
— Prestige Ascension: Reset your empire to gain Crown Sigils and unlock 7 permanent sigil upgrades that persist across every reign.
— Random Puzzles: Decode ancient ciphers, match rune pairs, and complete rune sequences for bonus rewards — but fail and suffer dark curses that weaken your circuit.
— Curse System: 6 different punishments drain your strength when puzzles fail — Weakened Strikes, Rusted Gears, Blood Drain, Empowered Foes, and more.
— Atmospheric Soundtrack: Three haunting dark ambient tracks with crossfade, plus pitch-shifted combat SFX.
— 20+ Steam Achievements: Track your progression from First Pulse to Hollow Sovereign.
— Steam Cloud Saves: Continue your reign across devices.
Can you rebuild the Hollow Circuit and claim the throne eternal?
