Completed the game within two days as I played it straight.
One question; Did anyone find that at the beginning cut scene of the asteroid crashing through the moon and hitting earth, did the voice crackle and got quieter at some points? Was this intended or is there something wrong?

Watch this video of the intro: http://www.youtube.com/watch?v=IBhffffQ-Sg

Then let me know if everything in that intro is what you, yourself, heard too. I've been seeing other in this section notifying of sound issues in the intro as well. If the intro in the link has the same audio that you heard then I might suggest looking up "sound design" or "sound effects" because the dialogue you've heard between the woman the the man was meant to sound like a radio transmission.
