Super fun! I found it a little frustrating at first, but managed to get used to it. I liked level 2. The music is cool too!
I think part of the clunkiness is that the grappling hook is a spring, which means it doesnt swing or let you gain much height (it instead tends to dampen your motion). But IMO this is actually okay, it just means its more difficult. It almost feels like jump king or something I'd watch a streamer play, where the aim is to get as far as possible before messing up.
Overall I think its a pretty original idea! And I think it fits the theme well
