This is an extra pack for Hanger 2, the cave-swinging game published by Notdoppler, with levels that keep coming. Press Enter to start, then throw your hook at the cave ceiling and swing yourself forward, one rope at a time.
The controls are the same as in the main game: the left and right arrow keys move the character, and the space bar throws the hook. Besides the regular levels there is an endless mode in which you also have to dodge monsters. The cave is not forgiving, so a steady rhythm beats speed: pick the next spot on the ceiling before you let go of the last one. New to the series? Start with Hanger 2 and come back here for more. Arkanoid Flash is another good Flash arcade game.
