Almost, but not quite, bug free
Fixed sound issues
Fixed EndScene crash

Turns out the sound issues were caused by my mishandling of music vs sounds. On Android and Linux only one "music" can play at a time. If you try to play a "music" as a "sound" then bad things happen. This allowed me to simplify the SoundManager significantly, thankfully.

I've confirmed that this version runs faithfully in Flash, Android, and Linux!
Moved InvaderGroup collision detection to the right place.
