Hey, first of all, thanks so much for playing it!
By the other hand, what you mentioned was intentional! The idea was to simulate having to grope around in the dark to find something you can't see (that's why we don't ask for a certain key). Having only one free hand means you can't use the lighter and search in the dark at the same time, so you have to put down the lighter first. The idea was to simulate the experience of being very limited in your movements in a dark place, but we know that because it's a bit unusual it's not always understood.
