Descend into darkness. Seal the sarcophagus. The realm gets another age.

A roguelike entry for the 7 Day Roguelike Challenge 2026.

You play a lone figure descending into mountain caves to seal an ancient evil buried deep below. Your lantern is your lifeline — fuel is finite, and the darkness is not empty. Gothic horror through resource scarcity and creeping dread, not jump scares.

• Traditional roguelike — turn-based, grid-based, permadeath
• Dual vision system — FOV and lighting are independent; you can see into darkness, but not clearly
• Lantern fuel as the central resource — your light radius shrinks as fuel runs out
• Sanity system that warps your perception of the world around you
• Risk/reward darkness — going unlit is dangerous but opens up tactical options
• Procedural cave generation with a hand-crafted tutorial floor

Brogue, Infra Arcana, Cogmind, Golden Krone Hotel, Castlevania

Built by porting and adapting systems from a closed-source personal roguelike project — reusing FOV, rendering, scheduling, and messaging patterns but building a fresh codebase for the jam.

Claude was used for documentation, best-practices discussion, and code review. All game code is written by hand.
