I love the use of the theme of the jam, and it is very original. It took me awhile to really understand, so I took time to read the page description and play around some more- I think if I continue to play it more I'd see the depth with added visuals, strategies and traps in the environment. There was clearly a lot of thought put into the concept, design and even the sound design as well.
I think the game could benefit from a more detailed tutorial or explanation, and despite opening in another tab for gameplay some of the HUD was cut off like the bosses HP (I probably should've just ran in full screen if it was available). It also would've been nice to have a sound track playing, something threatening to emphasize the feeling of being tethered and carried away.
Very good job overall, rated!
