Eclipse Core Client

The dungeon Grapple Hook has a new look: a three-pronged claw that flies out, bites into the wood and pulls a real rope behind it.
With the Eclipse client mod, the grapple now runs on your side, so it stays smooth even on a laggy connection.
Swinging is steered with your movement keys: W pumps the swing, S brakes, A and D swing you sideways, and you can look around freely.
Hold Space to climb the rope, hold Sneak to let it out, tap Space at the bottom of a swing to jump off, and use the hook again to let go.
Playing without the client mod still works as before, and the game tells you where to get the mod for the smoother swing.
