It was very intriguing and somewhat challenging, even, but I'm extremely leery of those laser cubes not having droppers to respawn them, especially down at the bottom where it's pretty easy to drop one into the water, rendering the whole test unsolvable in an instant. It didn't happen to me, but it easily could have, and that's concerning. I'd say it was another 3/10 on difficulty. Not a bad chamber, but maybe a little more insurance against having to start all over would be good, considering its length.

A laser puzzle I didn't hate. Thank you for not making a "hit these 9 relays with 2 cubes" geometry chamber.
This just took careful observation of what changes occur as you make connections. Fun map.

Design - 7/10
