This is a minor update, adding a bit of polish to the latest content:

1. Add new sound FX for:
   1. The Void
   2. Cougar Attack
   3. Snake Attack
   4. Fire, it now crackles
   5. Geiser bubbling and eruption
   6. Volcano bubbling
2. Red flash around the screen when taking damage
3. Minor tweaks to spawn-chances (making the world a bit more dangerous)
