Echo Sigil

Overview

Echo Sigil is a cooperative 2D top-down puzzle-adventure game featuring asymmetric magic systems where two players must work together to escape the sentient Eryndor Vault. Built using AI-first engineering principles, the game emphasizes intellectual puzzle-solving, cooperative gameplay, and narrative discovery through unique magical frameworks that require genuine collaboration.

Target User & Use Cases

Primary Users: Cooperative gaming enthusiasts, puzzle game players, indie game community members, and players who enjoy intellectually challenging games requiring teamwork.

Key Use Cases:

Local Cooperative Play: Two players working together on shared screen with asymmetric abilities
Intellectual Puzzle Solving: Complex glyph sequences and timeline manipulation requiring strategic thinking
Progressive Mastery: Learning curve from basic cooperation to advanced magic system combinations
Community Engagement: Sharing experiences and feedback through itch.io platform
Educational Cooperation: Teaching collaboration and problem-solving skills through gameplay
Indie Game Discovery: Supporting innovative cooperative game mechanics in the indie ecosystem

Core Features Implemented

Asymmetric Magic Systems

Auren’s Glyph Weaving System: Discovery-based glyph collection with visual sequence building interface
Sylis’s Shadow Echo System: Timeline manipulation (Past/Present/Future) with environmental integration
Cooperative Requirements: Neither player can solve puzzles alone - genuine collaboration required
Progressive Ability Unlocking: 15+ glyphs and 8+ echo abilities introduced across levels

Revolutionary User Experience

Discovery-Based Collection: Floating glyph pickups that auto-collect on touch, eliminating text input
Visual Timeline Feedback: Character and environment changes synchronized with timeline states
Intuitive Interface: Click-to-build glyph sequences with visual feedback systems
Professional Polish: Level completion popups with graceful navigation and progress tracking

Sophisticated Cooperative Puzzles

Data-Driven Configuration: JSON-based puzzle requirements enabling rapid level creation
Permanent Solution States: Solved puzzles remain solved, preventing frustrating re-work
Switch/Door Pattern: Extensible cooperative mechanics requiring both players’ unique abilities
Balanced Contribution: Impact tracking ensures both players feel equally valuable
