Line Color 2D

A calm but testing puzzle built around a single colored line on a flat circuit. You hold the control to slide the line forward, and your goal is to paint the whole route before you cross the finish. Moving obstacles keep interrupting the flow, so each stretch asks for a little planning rather than pure speed.

Part of the appeal is how much tension comes from such a simple idea. Watching the path fill in behind you is satisfying, and one badly timed push can undo a careful run. It mixes the feel of an arcade game with the patience of a logic puzzle.

Use the arrow keys to move the line around the circuit.

Keep the line moving so it covers the route without gaps.

Watch the moving obstacles and time your passes between them.

Reach the finish line only after the full path has been painted.
