Thank you for this amazing comment! I'm glad to see that you enjoyed my game.
Your suggestion of letting the player release mid grapple is an amazing idea that I will make sure to implement if I continue working on this game. When designing the game i thought that switching between having gravity in the ship and not having gravity in space could be a cool idea, so it's really cool that liked that mechanic :)
Lastly I would like to add that "Using them to reel myself into enemies and smash them with my face is possibly the best use of a grappling hook science has discovered so far." is from now on probably going to be this games tagline as it made me laugh when reading it.
