Swinging can mean several things; like an old man who likes dancing, or a creepy person into wife-swapping. Pendulumeca is a swinger game, but in a purer way.
All Pendulumeca asks you to do is to swing as far as you can along a spiky-floored corridor without smashing yourself to bits along the way. You do this by shooting a rope with a grappling hook into the ceiling and swinging along. Like a pendulum. Pendulumeca. Pendulum. Pendulumeca. Get it? Very clever. Pendulumeca isn't as easy as it looks, and that's mostly thanks to the annoying happy hardcore soundtrack.
