Cute little game, have seen others use the Only One Light source for there horror games, but nice idea to go with you have to transport a light-bulb to different lambs to get light. I will say it does feel like it can be a little tedious, Also feel there should be more indications on what lamb has the light bulb, you did make the light red when the power goes out, maybe you should have the lamps be empty cycles to indicate they don't have a light build on/in them. Also more indication of danger would be welcome.
P.S. the music in this game is an alternate vision of the music that I used in the Game Menu of the first main game that I posted on Itch.io
