Super fun and clever level design!
I found a small bug: if you grab a box that's next to a pole, you end up grabbing both, which causes you to clip with the box and get stuck. I had to restart the loop. I managed to reproduce it, so it seems to be consistent.
Other than that, the hook feels incredibly satisfying to use, and the environment is really well crafted . It gave me strong nostalgic Zelda vibes!
