This is a really clever way to make a grappling hook in a game interesting. I like how I need to drop the boulder before using the grappling hook but still go back for my boulder so I can do other parts of the level. The character does feel a bit floaty and that doesn't help with precise movement much but after making sure to plan out my movements and jumps I was able to get through some of the challenges presented to me in this game. Good job!
