NN666Path

NN666Path is a local offline puzzle game about reading a network, choosing a start node, and tracing every edge without reuse.

Play through a fixed set of handcrafted levels that grow in structure and difficulty. Early stages teach open loops and trail reading. Later chapters add fixed starts, ordered checkpoints, and one-way edges.

Features:
- 90 built-in levels
- Chapter-based level selection
- Continue the current trail later
- Daily challenge rotation from the local level set
- Hints for the next safe move
- Undo the last trail segment
- Failure review that shows where the route locked
- Level progress, favorites, recent best times, and completion badges
- Settings for drag assist, trail glow, sound cues, motion, theme, and helper arrows

The game stays fully offline and keeps progress on the device. There are no accounts, ads, payments, leaderboards, or external content.

Each level is designed to be solvable. Read the exits, follow the rules, and finish the full trail.
