Etherbound

Etherbound is a short and sort of experimental 3D first-person grappling hooks game with realistic chains physics and impulse-based collision damage.

In this game you take control of two grappling guns and a compressed-air jetpack system in order to navigate through unique environments and fulfil your sacred duty as a sentinel for the kingdom's border.

The game's central mechanic is very raw and physics based, thus it is harder to learn. It is somewhat meant to offer an almost simulation-like experience.
