Phones and computers

Silkline is a rope swing game that plays in the browser on phones, tablets and computers, for one player.

Swing a spider from street lamp to street lamp: hold to shoot silk, let go to fly. Silk drains while you hang and refills in the air, and every lamp you let go of goes dark. Touching the street ends the attempt; each of 30 levels rates your time in moths, then an endless mode opens.

Tips

A full silk meter lasts five seconds of hanging and refills twice as fast in the air, so short swings keep the thread alive.
Par on each level is the time a bot took to swing it; three moths need a finish within 1.15 times par, two within 1.5 times.
If the thread snaps at zero silk you cannot reattach until the meter is back to 0.15, and a press with no lamp in reach keeps trying for 0.15 s.

Which lamp does the silk go to?

The lit lamp within 340 px that is nearest to a point 110 px ahead of the spider, so the game favours the lamp in front over the one overhead. Lamps you have already let go of are dark and are never chosen again on that level.

What happens after level 30?

An endless mode opens. Press E, or tap the mode line on the start card, to switch between the levels and endless. Endless keeps adding lamps as you go and records your best distance in metres, while the levels keep their own moth ratings.
