Deceptive depth all around -- absolutely nailed it! There would be a place in my steam library for a casual puzzler with these mechanics.
I was more of a fan of the crate/barrel puzzles than the 'pure rope puzzles', and I think it's because the pixel art style, combined with the zoom level, makes it difficult to clearly make out the over/under, especially when the rope is over the template. Putting the template with partial opacity over the rope, and adopting a textured approach to drive home the shadows would have made it way easier on my eyes.
"Crosses" was the big difficulty spike for me. I ended up going back through the earlier puzzles again to see if I missed a mechanic. It eased up after that, so I'd be curious to find out if that was a common pothole for players.
I, of course, volunteer to playtest to help smooth out any difficulty spikes in your next endeavor :)
I spent longer on this than any other jam game so far, and I'm very happy with how I spent my reviewing time. Best of luck in the jam!
