DROP YOUR SOUND FILES HERE
==========================
Required:
  impact.ogg   - the boom / impact sound played the instant a black flash lands.

Optional:
  whoosh.ogg   - a layered whoosh (played quieter). Leave it out if you don't want it.

Notes:
  - Files MUST be .ogg (not .mp3 / .wav). Use Audacity, or any online
    mp3-to-ogg / wav-to-ogg converter.
  - File names must match EXACTLY (all lowercase).
  - ~0.3s - 1.0s long works best. Loud peaks are fine.
  - After adding a file, just (re)launch the game. No extra config needed.
  - Until you add impact.ogg the mod still does shake + hitstop + impact frames
    (it just stays silent).
