Straight to the point: Speed Demon is 4 traffic lanes starting at 360 px/s, 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.
Traffic scrolls down 4 lanes and never stops; you weave between cars, and the closer the pass, the bigger the near-miss bonus. Coins appear in risky places - exactly where you would rather not be - and the speed climbs the whole time.
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.
Weave through 4 lanes of traffic and grab coins.
Read Speed Demon as a Pecut Shelf game first and a Pecut Shelf game second. The shape explains how the session will end; the group explains what it will ask of you before that.
It is rated 4.4 out of five in our notes, and the number is held up mostly by how quickly it can be restarted rather than by how clever it is.
Keep it if you play in short bursts. It rewards a second attempt far more than a first, and the second attempt costs nothing but the tap.
