Loved the ambience but I also ran into some of the problems listed bellow. I think you are on to something but the game would benefit from some more love after the jam because there are some bugs (like the "how to play" button getting you to the credits or the radio) that are pretty annoying and take away from something that otherwise looks like a great technical achievement.
I also couldn't quite understand the game but I have a couple beers in me right now and I am lackign some sleep so I might come back to it later and try to play without turning on the radio (otherwise I might go crazy).
Overall good job! It just needs a little more work and you'll have something pretty great on your hands.
