I love the effects and general style you're going for here! It almost reminds me of Hotline Miami in a way. Cool aesthetic and a very neat idea of indirect gameplay.
Night 1 had a good amount of tension, however by night 2 I knew I was going to run out of power no matter what I did and that it was just reacting the same way to the same sound cues. I think with a bit more dynamism, interactivity, and resource management there could be a really solid game here.
