Mesmerizing game, this game shows the potential of having a team working together, the art is breath taking, the code working like a swiss clock and the game design solid. My biggest gripe might be that there isnt much left to do, the atmosphere carries the tension for the first bit but once you realize there is no real danger you just run around trying stuff.
The story was good although not being a native english speaker hurts the game with some weird phrasing. What i would wish for is more game mechanics, but not every game is heavy on that and it might be not the game for me after all.
On theme it sticks to Only one lightbulb and delivers on that fine.
On originality i've seen many spooky Unity games because of the easy light manipulation, that said this one has by far the best atmosphere hands down would love to see more from this dev.
