About Neon Snake
Snake, rebuilt with a neon glow and a grid that stays readable at speed. Steer with the arrow keys or WASD, or swipe on a phone; the snake never stops, so every turn is committed the moment you make it. Each pellet adds a segment and a point, and the trail behind you is the only real obstacle. Space restarts after a crash. Your best score is kept between sessions and posted to the leaderboard when a run ends.
