## What is Dot Trail Puzzle?

One Line Draw is a clean and relaxing logic puzzle about tracing every line exactly once.

Pick a dot, drag through connected paths, and complete the whole shape without repeating a segment. The rules are easy to understand, but each new level adds a sharper layout to solve.

Features:
- 50 progressively challenging puzzle levels
- Simple one-touch drawing controls
- Undo, restart, and numbered-node hint tools
- Local progress saving and level selection
- Original music and sound effects with switches
- Full-screen portrait gameplay
- Fully playable offline
- No accounts, no ads, no tracking, and no internet connection required

Take a quiet minute, read the shape, and find the one continuous path.
