Swapping lamps is a great idea, and a distinct take on the "one light" core. I think I was able to use a lamp that was on the other side of the wall. Check our game: https://cerosware.itch.io/one-stick-shooter
Thank you for your feedback :) It is indeed sometimes possible to reach lamps on the other side of the wall because we had to submit the game posthaste. We'll try to fix this in the next build eventually ;)
