Damn I really like the atmosphere it would be cool to see how you improve it as there are a few issues with gameplay. The monster seems to spawn completely randomly, rather than only when the lights are off I'm not sure if this is intentional though? It reminds me a bit of Iron Lung where you're trapped in an area and you have to carry out specific tasks. I think you should continue development as the idea of keeping the lights on is pretty unique and interesting.
