Rollerdash

A roller-skater dashes along a brick wall. Each push of the stick to the right, then let go, is one stride, and stride after stride builds speed, which slowly runs down by itself. Stick up jumps the low obstacles and stick down ducks under the hanging banners; hitting anything drops your speed to a crawl. Cover 1.00 mile before the timer runs out. You score 10 points for every 0.01 mile and 100 points for every tick left on the timer. There are ten levels, each with five ticks less, and when the time runs out the game is over.

Timing is the original's: its main loop ran about 18 times every sixtieth of a second, measured in a Commodore 64 emulator, and the port runs that loop 18 times a frame so that every rule counts in the original's units. The game riff is from the Commodore 64 version; the title tune is new.

Controls: either controller. Push the stick right and let go to stride; up jumps, down ducks.
