Straight to the point: Snake Turbo is a starting step of 95 ms that tightens as you eat, playable in your browser right now. It is tuned for quick runs, honest difficulty, and controls that make sense the first time you touch them.
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 95 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.
