Neon Serpent is a browser game built for short, satisfying sessions - it loads instantly, plays with one thumb, and runs on any mid-range phone. The setup is simple: a starting step of 130 ms that tightens as you eat. Nothing to install, no account, no waiting.
The snake moves in fixed steps; each pellet eaten adds length and slightly tightens the interval, so the game gets harder the better you do. Walls and your own tail both end the run instantly. The a starting step of 130 ms that tightens as you eat, and the ramp is tuned so mid-game still feels fair.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
Grow the longest snake without touching walls or tail.
