At first I couldn't see anything, and I accidently walked over to an object which caused a text bubble to appear. The UI text bubble was dark as well, so I thought the game may be messed up somehow. I then recognized that I was in a room and I figured out the lights. Then I realized I'm supposed to navigate the dark and not rely on the lights. It was a clunky experience. Usually in games with lights, being in the dark isn't the way to go, and since this wasn't that cliché usage of lightning, I think more of an explanation would be better. I was also concerned someone could play through the entire thing without realizing the lights even exist, which is why I said what I said.
