I didn't know what to expect when I started playing, but man did it deliver!

The light flickering was a great way to boost the atmosphere. The art was all on point. The sounds added even more to the atmosphere. AND it told a mysterious story. Well, kind of mysterious, I think I figured it out, but it was really cool having it all come together. I think the part in the vent where you get stuck was the most surprising moment, didn't know what to do and was definitely a shock. And near the end when you get all the pieces was the best moment, having the scene flicker from reality to that distorted perception.
