It was a unique experience, compared to all the other submissions I've played so far. Really loved the atmosphere! As already pointed out from others, I think the narrative was a bit confusing at times, and I only grasped more of it after reading your how does it fit the theme. And, even after reading that, I feel like the theme is only loosely incorporated (As the player, I didn't really feel the insanity and contaminants building up. The tension was, though! :D). Also, I think there should be a few more things to do (like the radio, that one was a nice addition), since I felt like I was mainly waiting for the next thing to happen whilst looking at the screen.
Definitely a very strong submission for this short amount of time! Good job!
