## The longest line Description
The longest line is a calm single-player puzzle game about reading routes, placing one decisive node, and watching colored water spread through a minimalist groove map.

Each level begins with a quiet network of grooves and several rival color nodes already on the map. Choose any valid position for your blue node. Once the placement is confirmed, every color begins to flow through the connected channels. The winner is decided by which color controls the longest length of the route network when the flow settles.

The rules are simple, but the maps become more demanding over time. Early stages teach spacing, timing, and bottlenecks. Later stages ask you to read branches, overlaps, and competing sources before committing to a single placement.

Features:

- 50 progressively harder offline levels
- One-tap placement with strategic route control
- Flow-length victory rules that are easy to learn and satisfying to master
- Minimal flat vector art inspired by clean transit-map design
- Soft pastel colors, crisp lines, and a calm visual rhythm
- Relaxing music and responsive sound effects with audio toggles
- No account, no network connection, no ads, and no in-app purchases

The longest line is designed for quick thoughtful sessions: a small puzzle you can understand at a glance, then keep replaying until the perfect placement clicks.
