This is a cool game with a neat interpretation of the theme!  I really like the art style and the voice acting is really neat, you don't see that in a lot of jam games! 

If you continue to improve it, I think two things would really help.  I think there should be some kind of visual feedback on blowing out lights.  It took me a long time to realize how long you had to hold the button for it to work.  Maybe the easier thing would be a small bar that fills or some effect on the character just to show something is happening.

I also got lost, particularly after the sleeping man in the first house.  You have to get really close to the door for the prompt to show up showing it's interactable.  I think I'd put some more indication on at least interactable doors.  I ran around that little house for a bit, I thought I had to go back out the way I came. 

Awesome submission, I'd love to see more from ya'll!

I dig the atmosphere! Got a little confused by the extinguish mechanic first, but then i kinda got it, i think.
