This is pretty great! It's cute, fun, and challenging. Very unique!
Some feedback:
The dirt on the far right doesn't read to me as being a vertical wall. I thought it was a flat ground, so I kept positioning the points here, thinking this was against the wall, when really there is still a huge gap. I think the lighting/shadows would be more helpful if they were immediately below the nodes and goats, as if the sun is at high noon.
This was a rewarding solution:
The final level was hilarious!
Well done!
