What BranchPy Helps You Detect
Spot structural and media problems before they become production blockers.
Broken or unreachable paths
Gameplay and narrative: missing transitions, orphan labels, dead-end paths.
Missing or mismatched media
Absent references, unused assets, project-to-file mismatches.
Structural risks
Fragile dependencies, hard-to-maintain architecture, high-risk areas.
Logic and structure inconsistencies
Questionable variable usage and branching structure, surfaced for your review.
