Gameplay
Grappling Hook has little plot. The object is to complete the challenges set by a malicious computer. Play is focused on speed. The player begins in the first of 31 three-dimensional stages, which are viewed from the first-person perspective, tasked with reaching the exit.
The exit will only open once diamond-shaped passcodes have been collected from around the current stage. The titular grappling gun is acquired after the earliest stages have been completed. Moving platforms must be crossed, health-depleting electrified panels must be avoided, and green surfaces can be grappled in order to swing towards the stage exit. In later stages, defensive turrets begin to appear, firing directly at the player-character, and swinging with the grappling hook also becomes more difficult, requiring the player to time the release of the grappling hook very precisely.
Development
SpeedRunGames is a one-man development outfit run by computational visualistics student Christian Teister. Having studied since 2001, Teister developed some small video games before being hired to work on the stealth video game Velvet Assassin during 2008 and early 2009. Work on Grappling Hook began after the developer finished work on Velvet Assassin, development of Grappling Hook began in March 2009. The previously created smaller games gave Teister the experience necessary to undertake Grappling Hook. One, a mobile game named Gladiator, provided the animation system used in Grappling Hook.
Grappling Hook was inspired by a Half-Life mod called Cold Ice. Teister wanted to build on the "feeling of acceleration and velocity" from Cold Ice with the use of the grappling hook; "I think the spatial puzzles are perfect to encourage the player to explore how the grappling hook can be used."
