I'm glad I found this one before the end of the jam!
Really fun writing and a great mechanic.
I found the physics of the rope swinging a bit wonky at times. The generous checkpoints made up for any troubles I had, however. I'm also rather bad with grappling hook mechanics in games generally, so take what I say with a grain or two of salt.
The music and the ever optimistic worm kept things fun and lighthearted no matter how many times I fell into a pit.
