Pen Fight Turns a School-Desk Flick into a Browser Duel

Field notes

The game places a red player-controlled pen and a blue computer-controlled pen in an 800 × 500 HTML5 Canvas arena. Shots use a drag-opposite-and-release gesture, with collisions, bouncing, and friction determining each turn. A local score board accepts a name, score, and optional tactic note, then groups results into ranges from 0–2 points through 10+ points without submitting entries to a public server.
